What Your Body Says About Your Health

By Sally Wadyka
health and body

There’s a lot you can say about your body, of course—from “I’m too fat!” to “Check out these abs!”—but there’s a lot your body can say about you, too. Yellow fingernails are a warning sign for lung cancer and diabetes.  By falling out, your hair may be telling you that you’ve got an iron deficiency. And there are plenty of reasons why your doctor wants to get a close look at your tongue. It’s a good idea to listen to what your body has to say—your good health depends on it.

What Your Nails Are Telling You About Your Health

A perfectly manicured hand is one where the nails are strong and smooth, with no discoloration, jagged cuticles or other signs of abuse. But what about nails that are less than perfect? Since many health problems have an impact on the nails, it’s worth listening to what your hands have to say.

The pits
When the normally smooth surface of the fingernail has several small dents or pits in it, that can be a signal that something is going on beneath the nail. Most often, the cause of those dents is psoriasis. The inflammatory skin condition—it shows up as red, scaly patches on the skin—can also affect the skin cells in the nails. Instead of growing out smoothly, the surface of the nail takes on a dented appearance. Once the psoriasis is treated and under control, nails will slowly return to normal. (Since nails only grow about a millimeter per week, it will take a few months for the old, pitted nail to fully grow out and be replaced with a healthy one.)

Spoon-shaped
A healthy nail has a specific shape—slightly raised in the middle, then curving down a bit at the tip. So when you see a nail with the exact opposite configuration, that should be a clue that all is not right. “It’s called a spoon-shaped nail, and it’s a symptom of iron deficiency anemia,” says Dr. D’Anne Kleinsmith, a spokesperson for the American Dermatological Society. As with many health problems, it can take months of iron deficiency before the problem shows up in the nails. And when the anemia is corrected, it will take awhile for normal-shaped nails to re-grow.

Peeling
The nail plate is made up of several layers of keratin (a protein). Ideally, those layers are sealed together to form a unified, strong nail. But when nails aren’t protected—your hands are in water a lot, or exposed to cold, dry air—those layers tend to delaminate. The result is nails that are likely to peel. Besides being an indication that you need to take better care of your nails—polish can help seal the layers and moisturizing them several times a day will keep the layers supple—peeling nails can mean a diet that’s lacking in linoleic acid. The easiest way to up your intake is to increase your use of vegetable oils (add some to your salad dressing or drizzle some on steamed veggies).

Brittleness
By some estimates, about 20 percent of women suffer from a condition called “brittle nail syndrome.” While it may sound like just a fancy name for nails that break easily, the causes go deeper than that. Brittle nails are ones that can’t hold on to moisture, so the layers of the nail plate dry out and crack. Medically speaking, it’s possible for an under-active thyroid to cause both dry skin and brittle nails. Nutritionally, a diet low in iron can cause nails to become thin, brittle and easily broken (eating more green, leafy vegetables, red meat and eggs will help boost your iron intake). Biotin supplements (a B-complex vitamin) have also been shown to improve the condition of brittle nails. And your habits play a role as well. The main culprit: excessive exposure to water. Constantly wetting and drying your hands (and nails) can make brittleness worse.

Looking yellow
A healthy nail (with healthy skin beneath its bed) has a pretty, pinkish hue. When it doesn’t, that may be a reason to worry. “When all of the nails turn yellow it can be a sign of lung disease or diabetes,” says Dr. Arielle Kauvar, a New York City dermatologist. “Yellow spots on the nails can be an indicator of fungus or psoriasis.” Since any of these conditions warrants treatment by a doctor, it’s worth seeing a dermatologist if yellow nails persist. Women who frequently wear very dark nail polish for long periods of time (especially without using a protective basecoat underneath it) may also notice a slight yellowing of their nails, but it’s no reason to panic. The nails are merely stained from the polish and will return to their normal shade if they are left unpolished for a while.

White spots
Tiny white splotches dotting otherwise healthy-looking pink nails are not normally a sign of anything serious. Most often, those spots are the manifestation of some type of trauma to the nail. If you injure the nail matrix—the area at the base of the nail where new nail cells are created—you’ll see the results of that trauma show up as white spots as the nails grow out. But since it takes several weeks for those new nail cells to grow out to a place on the nail plate where the injury is visible, chances are that by time you notice a white spot, you may have forgotten the nail-slamming incident that caused it. But if you’re certain you didn’t injure your nails and you are noticing recurring white spots, there are several other causes—including the skin conditions psoriasis and eczema, or a diet that’s deficient in the mineral zinc (found in whole grains, poultry and seafood).

Turning colors
The most common cause of fingernails that suddenly take on an unhealthy tinge is some type of fungal infection. Both yeast infections and bacterial infections can easily be picked up at an unsanitary nail salon—usually caused by the use of unsterilized tools. “A yeast infection can cause the nail to separate from the underlying skin,” says Kleinsmith. “The nail can start lifting up and a crumbly, white fungus can appear underneath it.” A bacterial infection can cause the affected nail to turn slightly green. And getting too vigorous with the cuticle pusher or nippers can lead to either a yeast or bacterial infection in the cuticle surrounding the nail. “If you notice sudden swelling or pain in the cuticles a day or two after a manicure, see a doctor to get on antibiotics,” she recommends.

The half moon
Officially called the lunula, that little crescent at the base of the nail is where the nail matrix (the birthplace of new nail cells) lies. Normally the lunula is most prominent on the thumbs, and it gets progressively less visible on each finger as you move from thumb over to pinky. “It’s a normal variation to see more of it on some fingers than on others,” says Kleinsmith. “And whether it’s visible or not isn’t indicative of health.” A fun nail fact: the shape of the lunula determines the natural shape of the nail edge.

Ridges
Potato chips aren’t the only things that can have ridges. Nails that have even, vertical ridges are totally normal—a sign not of any health problems, but of age (they tend to become more accentuated as you get older). But a condition called Beau’s lines is a sign of a more systemic health issue. “If a person has been very sick or gone through a lot of stress, the nail may stop growing,” Kleinsmith explains. “When it starts growing again, an indentation occurs at that spot on the nail.” As the nail grows out over the next several months, these indentations (probably in about the same place on each nail) will become visible. A single deep ridge in just one nail may indicate that there’s a small wart or cyst at the base of the nail that is putting pressure on the nail matrix and affecting the way the new nails grow.

What Your Tongue Is Telling You About Your Health

You may not give your tongue much thought, but chances are your doctor does. “Telling a patient to stick out their tongue is a valid way to start examining someone,” says Dr. Jordan S. Josephson, attending physician at Lenox Hill Hospital in New York City and author of Sinus Relief Now. “In fact, in Chinese medicine they believe that the tongue actually reflects all the diseases of the body.”

White coating
When the tongue looks sort of white and pasty—in patches or in its entirety—it’s an indication that there’s probably some sort of infection present on the tongue, such as a bacterial overgrowth or an autoimmune-related inflammatory disease. One possible cause: Thrush, which is an overgrowth of candida (also called yeast) bacteria. Once the infection is treated with anti-fungal drugs (either topical or oral) and the infection clears up, the tongue will return to its healthy pink shade.

Too dark
A healthy tongue should have a warm, pinkish color, so when it looks dark brown or black, you need to wonder why. And chances are, the answer will be in your diet, lifestyle or your medicine cabinet. “The filiform papillae on the top of the tongue—particularly if they’re elongated—can easily take on stains or various colors from the foods, drinks, antibiotics, lozenges, etc. that you consume,” says Sol Silverman, Jr., DDS, a spokesperson for the American Dental Association. A side effect of taking bismuth medications (like Pepto Bismol) is that the tongue may turn temporarily black. And drinking a lot of coffee, smoking or chewing tobacco can stain the tongue a brownish shade. The good news is that in both cases, it’s probably just stained from food or medicine, and simply brushing your tongue a few times should help it fade back to its normal shade. While the staining may not be permanent, beware that any kind of tobacco use increases your risk of oral cancer.

Getting hairy
“The top of the tongue is covered with little projections called filiform papillae,” explains Silverman. “They’re made up of keratin—the same protein that makes up hair, but they’re not really ‘hair.’” And under normal conditions, you wouldn’t even notice them. But certain conditions can cause them to elongate, giving the tongue a “hairy” appearance. Several factors could be responsible for causing the filiform papillae to grow, including a bacterial infection, taking antibiotics, or having a very dry mouth.

Sore spots
They may be small, but canker sores or mouth ulcers (which can occur anywhere in the mouth, including the tongue) can be extremely painful. “Most things that happen in the mouth are multi-factorial,” says Silverman. And these sores are no exception. Generally, those with a genetic predisposition to getting cankers will see them crop up when other factors fall into place—such as having a cold or fever, eating an excess of citrus fruits, or biting your tongue. But keep an eye on those spots. A normal canker will heal up and vanish in a week to 10 days. Something that lasts longer and doesn’t seem to be going away could be a sign of oral cancer and should be checked out by your doctor immediately.

A bumpy surface
The filiform papillae—projections on the top of the tongue, including the taste buds—normally stick up a little bit. But occasionally one will get temporarily inflamed, red, and a bit sore. As with canker sores, as long as the area returns to normal within a time span of a few days, the inflammation is most likely harmless. “But if it turns very red or white, is painful and tender, and most importantly, doesn’t go away, it could be a sign of oral cancer,” Josephson warns.

Red and painful
When the tongue’s healthy pink color mutates to bright or dark red, that can be clue to certain nutritional deficiencies—especially a lack of niacin (also called vitamin B3), a condition known as pellagra. Other nutritional issues can also cause this odd coloring. Anemia or a diet lacking in folic acid and vitamin B12 may be to blame. But a temporary redness and pain in the tongue is most likely caused by something you ate or drank. Sensitivity to certain flavors of toothpaste, mouthwash or gum (like cinnamon) and acidic foods (like pineapple) are potential culprits. If you suffer from frequent bouts of tongue pain, you might want to try eliminating these foods from your diet to see if the irritation clears up.

Turning yellow
A yellowish tint on the tongue is probably a clue that there is some sort of fungal or bacterial infection in the mouth. Another possible cause of tongue yellowing is gastric reflux. “It may be that the acid rearranges the mouth’s normal bacterial flora, and some of it may have a yellow hue,” says Josephson. Occasionally, changes in the tongue’s color will happen only in patches—a condition known as “geographic tongue.” In that case, some spots on the tongue will become yellow while other areas remain normal and pink.

A burning sensation
Burning mouth syndrome, also called oral dysesthesia, is a specific, not well-understood condition that goes far beyond simply eating certain foods that cause a temporary stinging sensation. The condition is characterized by pain and burning that can affect just the tongue or the entire mouth; the sensation may be constant or it may come and go throughout the day. For reasons that are not clear, burning mouth syndrome most commonly afflicts post-menopausal women. “It could be some damage to the nerves of the tongue that are somehow related to the hormonal changes of menopause,” Josephson says. Other possible causes include bacterial infections, dry mouth (a side effect of some medications), or nutritional deficiencies. A cure is elusive, but some of the current treatments for managing burning mouth syndrome include drinking water more frequently, chewing gum (to combat dry mouth), or taking anti-anxiety or anti-depressant drugs.

Pale and smooth
When people are suffering from iron deficiency anemia, the tongue can take on an abnormally pale, smooth look. “That’s because when your body is dealing with a lack of iron, your blood doesn’t have the necessary oxygen-carrying capacity to keep the tissues red,” explains Josephson. And the result of that lack of oxygen in the blood is that all of the tissues—including the tongue—become pale and look, well, anemic. When the anemia is under control and the blood is once again well-oxygenated, the tongue will go back to its healthy pink shade.

What Your Hair Is Telling You About Your Health

A healthy head of hair is easy to spot. It’s full, shiny and lustrous with no flakes, frizzies or other visible damage. But what about when your crowning glory isn’t quite so glorious? In some cases, it might be a harbinger of health problems—or it could simply mean that you’re spending too much time with the blow dryer.

What Your Bowel Movements Are Saying About Your Health

It may not be a topic typically talked about at the dinner table or a cocktail party, but most people are actually somewhat obsessed with it. And with good reason: The state of your gastro-intestinal tract (as well as the quality and quantity of its output) is a great barometer of the health of your body

Hard and dry
The amount of time it takes for the food you eat to make its way through the gastro-intestinal system and exit into the toilet will have an impact on the consistency of your stool. “Intestinal transit averages 40 to 45 hours from when you eat to when it comes out,” says Foxx-Orenstein. If it stays in the GI tract for longer than that, fluid is re-absorbed into the body and the stool becomes harder and dryer. Certain medications—like blood pressure drugs, antidepressants and histamines—can slow down the GI tract. Constipation, which has a myriad of causes, will lead to harder, drier stools (since you’re going less often, your stool will stall in the system and the fluid re-absorbed). For some people, a diet high in dairy can be a cause of constipation, so if you are experiencing problems going (and have dry, hard-to-pass stool when you do finally go), it is worth reducing your dairy intake for a week or two to see if that helps. And being dehydrated can also lead to this problem because if the body is lacking in water, it will draw it—and conserve it—from wherever it can find it.

Little lumps
“An ideal stool looks like a torpedo—it should be large, soft, fluffy and easy to pass,” says Foxx-Orenstein. But when conditions are less than ideal, the stool may become more like little deer pellets. Again, transit time may be part of the issue because slow-moving stool will lose fluid, making them less fluffy and lumpier. A lack of fiber in the diet may also to be to blame. Beware if you’re following a weight-loss plan (such as Atkins) that focuses on increasing protein and decreasing carbohydrates, since that can leave you with a diet that’s low in fiber. And since fiber holds on to fluid, a lack of it will lead to harder, pellet-like poops that may be more difficult to pass.

Too liquid
Your body secretes about eight liters of fluid during the course of a day—from the stomach, salivary glands and pancreas—to help your food get broken down and make its way through the digestive system. Under normal, healthy conditions, the majority of that fluid is absorbed along the way, resulting in those sought-after soft, fluffy stools. But if food passes through too quickly, there isn’t enough time for all of that liquid to absorb, and the stool emerges in a too-soft state. The reasons for such super-quick transit could include a sudden increase in fiber in the diet, or a bacterial or viral infection. “When there is an infection, the body produces toxins which cause water to be released,” says Dr. Michael Farber, director of the Executive Health Program at Hackensack University Medical Center. “Things move through very quickly through your system because the body wants to get rid of them.”

Pencil thin
Thin may be the preferable state for many things—figures, cell phones, television screens—but when it comes to bowel movements, thin is definitely not a good thing. Specifically, thin stools could be an indicator of colon cancer, or its precursor, polyps in the colon. “Whenever you have mass in the colon that creates blockage, anything that needs to be pushed past that mass will become thinner,” Farber says. “If you are seeing thin stools on a consistent basis, that it something you should have looked at by your doctor.”

Looking pale or gray
Normal stool can come in a range of colors (influenced by what you eat and what medications you take, among other factors). But if your stool has an unhealthy hue, particularly if it’s pale or grayish in tone, you could have problems somewhere along your digestive tract. The liver excretes bile to help break down fats in the food you eat, and that bile also adds color to the stool. But if there’s a blockage in the liver—or in the tubes through which the bile travels—the stool might take on a too-pale appearance. Also, if you are suffering from a pancreatic disorder, the stool might look gray because it will be lacking the color imbued by the digestive enzymes produced in that organ.

Bright red
Your first instinct upon seeing red-colored stool in the toilet would probably be to panic. But before you speed-dial your doctor, think about what you ate several hours ago—if it was beets or bright red popsicles, that might be the culprit for creating those colored stools. But if it’s obviously a streak of red blood in the stool, in the toilet, or on the toilet paper, then it’s a given that you’re bleeding somewhere inside. There’s still not necessarily any reason to panic—the cause could be something as benign as a hemorrhoid or just a small fissure caused by straining to go. That said, it’s a wise idea to discuss with your doctor if you are straining often since that can lead to painful hemorrhoids. Also, if you’ve never seen blood before it’s definitely worth having your doctor rule out more serious causes—like colon cancer.

Too dark
If your stool is suddenly black and looks sort of tar-like, the culprit could be lurking in your daily vitamin pill. Iron supplementation (on its own or when it’s included in a multi-vitamin) can have that effect on the stool. But if you haven’t recently started taking extra iron and you see this sort of change, you should make an appointment to see your doctor. “If there is bleeding higher up in the GI tract—like the stomach or esophagus—the result can be stool that looks black and tar-like,” says Foxx-Orenstein. “It’s very useful information for the doctor to know if what you’re seeing is black or bright red because that gives a clue to the location of the bleeding.” In either case, she strongly urges anyone who is seeing blood in their stool to get checked out by their doctor.

It floats (and stinks!)
Those ideal torpedo-like poops should sink when they hit they hit the toilet. But when the body isn’t properly absorbing fat from the food you eat, it ends up being excreted in your stool. The result: stool that’s yellowish in color, greasy in consistency, foul smelling, and that floats in the toilet. Certain medical conditions, like celiac disease, can cause these malabsorption problems. And since essential nutrients could also be lost along with the un-absorbed fat, it’s important to see your doctor if you experience this problem. These fatty, smelly stools are also one of the more unpleasant side effects of eating foods that contain Olestra (the faux fat found in some chips and other fried snacks) or of taking the weight loss drug Xenical or its over-the-counter cousin, Alli.

Not going
How often is normal? How much is too much? Or not enough? Everyone wonders if they’re spending too much—or too little—time on the toilet. Turns out, there is no one right answer. “There is no true ideal for how frequent your bowel movements should be,” Foxx-Orenstein says. “What’s ‘normal’ is going to be different for different people.” Once a day, three times a day, every other day—all of these could very well fall within the definition of normal and healthy bowel movements. But if you experience a change in your normal pattern, then you need to look at what might be causing it. If you’re suddenly going too much, it could be because you’ve recently increased the amount of fiber in your diet. That’s a good thing, but it will take the body a little while to adjust to the change. And if you are suddenly dealing with constipation, look first at what changes you’ve made to your diet. “If you’re not eating enough fiber, not eating breakfast [which helps get things moving in the morning], or just not eating enough food, you may be constipated because your body’s not able to produce enough waste,” says Foxx-Orenstein.
