Signs from your body

Maybe you’re losing more hair or gaining some extra weight. Perhaps you’re always tired or your partner says you snore. There are probably harmless reasons for these everyday happenings. But maybe there’s something more serious going on. From gassiness to sleepiness, muscle cramps to weirdly colored nails, here’s a look at some hidden signs you might not be as healthy as you think.

You’re bloated

Just because you follow doctor’s orders—you eat your greens, choose organic when you can, exercise regularly, and get eight hours of sleep each night (err, most nights)—doesn’t mean that your health is in the clear. You may think your post-dinner bloat is totally normal, but sometimes a subtle symptom like that can signal a more serious health issue.

Simple reasons for bloating include constipation, overeating, or reflux. More serious causes include infection, inflammation, irritable bowel syndrome, Crohn’s disease, and some medications.

“When you eat too much, or you eat food you’re not supposed to eat, you’ll have temporary discomfort, and you might not feel good for 20 or 30 minutes,” says Tasneem Bhatia, MD, a board-certified integrative medical expert in Atlanta, and author of Super Woman Rx. “But then it usually dissipates, as the digestive system takes over.

“A one-time thing is easy to ignore as long as the pain isn’t lasting,” says Dr. Bhatia. But “if it happens more than three times, or if the pain lasts more than 12 to 24 hours, you need to be examined by a physician.”

You snore

Snoring happens when air can’t move freely through your mouth and nose as you sleep—the muscles in your throat relax and your tongue can slip back in your throat—and can be caused by adenoids, nasal polyps, or even just a stuffy nose. If you’re overweight or have had a lot to drink, you’re more likely to snore.

“Snoring can also be a sign of obstructive sleep apnea,” says Albert Wu, MD, director of the Center for Health Services and Outcomes Research at Johns Hopkins Bloomberg School of Public Health in Baltimore. That’s when your upper airway becomes blocked repeatedly while you sleep, causing you to partially or completely stop breathing for a few seconds. “The resulting disruption of sleep can lead to daytime sleepiness, crankiness, difficulty concentrating, high blood pressure, and heart conditions.”

How to know if your snoring is cause for concern?

“If your partner notices that you stop breathing for long periods of time, you should consult a specialist,” says Dr. Wu. “Treatments for simple snoring include losing weight, treatment for allergies, sleeping on your side instead of your back, and avoiding alcohol before bedtime. If snoring is caused by sleep apnea there are dental mouthpieces that keep your airway open, and continuous positive airway pressure (CPAP) masks that direct pressurized air to keep your airway open during sleep.”

You’re gassy

Believe it or not, passing gas 13 to 21 times a day is normal. A lot more or a lot less than that could indicate a problem. 

“Not passing gas indicates that your bowels aren’t functioning properly, but passing gas too much or too often can indicate a food intolerance, or a digestive disorder like gastroesophageal reflux disease (GERD), Crohn’s disease,  irritable bowel syndrome (IBS), or celiac disease,” says Dr. Wu. “You should see a doctor if you have persistent and unexplained flatulence. You should also do so if you have symptoms along with it, such as abdominal pain, a swollen stomach, vomiting, diarrhea, constipation, unintended weight loss, severe heartburn, or blood in your bowel movements.” (Check out these 10 surprising foods that cause gas.)

You’re always tired

If you always feel lethargic (no matter how many hours of shut-eye you get), it’s definitely worth talking to your MD. Unlike drowsiness, which is the need to sleep, fatigue is lack of energy and motivation. It can be a normal response to lack of sleep, lots of physical activity, stress, or even boredom. But fatigue can also be a sign of a number of health problems.

“Missing sleep, almost any illness, and many medications can cause temporary fatigue,” says Dr. Wu. But “persistent fatigue can be caused by a number of serious conditions including anemia, chronic kidney disease, liver disease, cancer, thyroid disorders, chronic infection, and arthritic conditions. It can also be caused by depression and anxiety disorders.”

You can’t sleep

It’s one thing to have trouble falling asleep when you just aren’t tired, but if you can’t get any Zzzs despite feeling exhausted, it’s worth bringing up with your doctor. Acute insomnia is short term and can be brought on by stress at work or at home or a traumatic event. 

Chronic insomnia, on the other hand, “is a common problem, and can simply be a sign of aging, lack of activity, or consuming too much caffeine, nicotine, or alcohol,” says Dr. Wu. “It can also be caused by medications like cold remedies that include stimulants, some antidepressants, and medications for asthma or high blood pressure.”

Other causes of insomnia include “mental health problems like anxiety and depression,” says Dr. Wu. “It can be a sign of some medical conditions like chronic pain, overactive thyroid, GERD, heart disease, Parkinson’s and Alzheimer’s disease.” (Here are 15 more silent signs your body could be in big trouble.)

You have bad breath

Bad breathor halitosis—is the most common reason for dental referrals, after tooth decay and gum disease, according to a review of studies published in 2018 in The Open Dentistry Journal. Sure, the culprit could be all that garlic you consumed at your last meal. But sometimes bad breath is a sign of something more serious. 

Usually caused by bacteria on your teeth and tongue, bad breath can be linked to poor brushing and flossing habits, or oral issues like dry mouth, gingivitis, or periodontitisIn some cases, sinusitis, bronchitis, tonsillitis, and some gastrointestinal issues can also trigger bad breath. If brushing and flossing doesn’t help, see your doctor or dentist.

You get headaches regularly

Besides being a pain (literally), headaches—the most common form of pain, according to the National Institute of Neurological Disorders and Stroke—are often pretty harmless. But some headaches are more serious than others. Talk to a doctor if a headache is sudden and severe or is accompanied by a stiff neck or follows a blow to the head or pain in your ear or eye. Get medical attention if you have a headache and fever, convulsions, confusion, or pass out or have a fainting episode. If you’ve never had a headache before and suddenly have your first, it’s time to ask your doctor what’s up.

Your muscles cramp up

Everyone suffers from a muscle cramp now and then, especially after a tough workout; in fact, a review of studies, published in 2018 in Journal of Electromyography and Kinesiology, suggests that exercise-associated muscle cramps are the condition most often requiring medical treatment during sports.

But some conditions can increase the risk of having leg cramps, like being dehydrated, having low levels of electrolytes, taking certain medications, having a nerve disorder, or an underactive thyroid gland (hypothyroidism). A review of studies published in 2019 in European Journal of Neurology found that many aspects of cramping are not completely understood. Pay attention to when and how often you have muscle cramps so your doctor can determine the potential cause.  (Check out these 5 hidden muscles that are causing you pain.)

Your nails are a funky color

Nails are supposed to be pink, so if yours are venturing into any other color category, speak to your doctor. Funky-colored nails could be harmless, according to the American Academy of Dermatology; but it could also be a sign of various skin disorders, if not something more systemic, according to research, including a study published in 2015 in Indian Dermatology Online Journal.  

Blue nails can mean you’re not enough oxygen in your bloodstream. White can signify liver disease or diabetes. Yellow nails can signify a nail infection or liver disease. Dusky red half moon could be a sign of heart disease, arthritis, lupus, alopecia areata (an autoimmune skin disease), or an inflammatory disease known as dermatomyositis.

You’re losing weight

Of course this doesn’t apply if you’ve started a new diet or exercise program. But “if you’re not trying to lose weight and you’re losing more than five pounds without any effort then you need to see a doctor,” says Dr. Bhatia. “The five-pound rule is a pretty safe guide—almost everyone I know fluctuates that amount—but  if you’re having progressive steady weight loss, that’s something bigger and needs to be seen.”

You can blame weight loss on all sorts of disordersfrom stress and chronic illness, to digestive disorders and infections, to chronic anemia and cancer, says Dr. Bhatia. See a doctor if you’ve lost more than 10 pounds (or 5 percent of your normal body weight) over a span of six to 12 months or less, and you don’t know why. (It could be one of these 20 reasons for dropping pounds unexpectedly.)

You’re gaining weight

Just like unexplained weight loss, unexplained weight gain is also something to see a doctor about. “Many people will dismiss it,” says Dr. Bhatia. “They think they can get a handle on it and before they know it 10 pounds has turned into 20 has turned into 30.”

It could be a sign of an underactive thyroid, polycystic ovarian syndrome, or Cushing’s syndrome. Did you start a new medication? Lots of drugslike corticosteroids, birth control pills, diabetes meds, and some drugs used to treat bipolar disorder, schizophrenia, and depressioncan cause you to gain weight. If you see your doctor at the 10- or 12-pound mark, it’s much easier to reverse it,”  says Dr. Bhatia. (Here’s how to avoid weight gain when the gym is closed.)

You have a low libido

If you never feel like getting frisky between the sheets, you might want to talk to a healthcare provider about it. You wouldn’t be the first. “It’s a common complaint I get from women, but it’s increasingly common in men,” says Dr. Bhatia. “Women are overwhelmed and exhausted, and since libido is tied into emotions, we see libido go down if there’s a disconnect from themselves or their partners.” 

As for men, Dr. Bhatia blames what she calls “the estrogenization of men,” which happens when there’s “a convergence of high stress, very poor lifestyle habits, and weight gain,” she says. As a result, “it’s almost like men are dropping their testosterone level faster than they did in the past and that’s affecting their libido.”

Having a low libido can be totally normal, but it can also be caused by a hormone imbalance, depression, or certain medications. (Check with your doctor if these natural libido boosters don’t work.)

You’re losing a lot of hair

Shedding between 50 and 100 strands of hair per day is normal, according to the American Academy of Dermatology. But if you’re losing more than that, “you should call your doctor,” says Dr. Wu.

Hair loss can be a normal consequence of aging, heredity—especially for men—or hormone changes, but it can also result from medical conditions,” he says. Those include “scalp infections, thyroid disorders, immune disorders, and sudden traumatic events.  Certain medicines can cause hair loss including some for cancer, arthritis, high blood pressure, or heart disease.” (Learn about more things your hair can reveal about your health.)

You’re not regular

If you’re eating a high-fiber diet and drinking a lot of water, and you’re not pooping regularly, take note. “The digestive system needs to empty to reset for other things and when it doesn’t there’s a shift in bacteria that then drives inflammation, which leads to chronic disease,” says Dr. Bhatia. “So the gut is ground zero for health.”

Of course, “regular” means different things to different people—the National Institute of Diabetes and Digestive and Kidney Diseases defines constipation as fewer than three bowel movements a week—so a change in pattern is what matters. “Chronic constipation or trouble emptying could be a sign of colon issues, thyroid disorders, irritable bowel syndrome, hormone imbalance in women, autoimmune disease—the list is pretty long,” says Dr. Bhatia. “If you go three or four weeks without having a bowel movement, you need to talk to your doctor.” (Your bowel movements can reveal a lot about your overall health.)
