8 Signs of Excessive Underarm Sweat

Everyone sweats when they get too hot, but if you're frequently dripping in sweat for no reason, you could have hyperhidrosis, a treatable medical condition. By Beth W. OrensteinMedically Reviewed by Justin Laube, MDReviewed: January 5, 2018Medically ReviewedDo you find yourself wondering why you sweat so much? Relax. Everyone sweats. "Sweating is a normal response to heat or anxiety," says Hunter Q. Kirkland, MD, a cardiothoracic surgeon at Cardiothoracic and Vascular Surgeons in Austin, Texas. But while sweating is the body's way of cooling off, some people sweat excessively — sweaty armpits, sweaty necks, and sweaty, smelly feet — and for no apparent reason, making them feel as though they're living in a sauna 24/7. This may be due to a diagnosable medical condition called hyperhidrosis, which affects almost 3 percent of the population, or about 8 million Americans. Normally, we sweat to cool our body and control our body’s temperature. But too much sweat can cause stained shirts and body odors, affecting social relationships and even self-esteem. According to the Mayo Clinic, hyperhidrosis (high-purr-high-DROE-sis) is abnormally excessive sweating that's not necessarily related to heat or exercise. People with hyperhidrosis sweat so much that it soaks through their T-shirts or drips off their hands. Besides interrupting a normal life, hyperhidrosis can result in major embarrassment and social anxiety. The most common type of hyperhidrosis is primary focal or essential hyperhidrosis, in which the nerves that trigger your sweat glands become overactive. Even if you aren’t running or hot, your feet, hands, or face will sweat. A more serious type of abnormal sweating is called secondary hyperhidrosis, which signals a dysfunction of the central or peripheral nervous system. This type of excessive sweating is generally the result of a medical condition including:DiabetesHeart attackInfectionsLow blood sugarMenopausal hot flashesNervous system disordersSome types of cancerThyroid problems Though excessive underarm sweat isn't serious or life-threatening, it can be embarrassing and make you uncomfortable and anxious. There are medical treatments for hyperhidrosis, but you’ll need to make an appointment with your primary care physician. Common treatments for excessive sweat include:Anticholinergics or drugs that block the body’s sweat triggerBotox injections to block the nerve signals that trigger sweatPrescription antiperspirantsSurgery (usually endoscopic thoracic sympathectomy [ETS]) One study published in the American Academy of Dermatology found that primary hyperhidrosis increases the risk of bacterial and fungal infections on the skin. So, if your excessive sweating seems too much, see a doctor to get back in control and avoid possible infections. Here's how to tell whether you are exhibiting signs of hyperhidrosis or if your sweating falls into a normal range.1694

Armpit Sweat Makes It Impossible to Keep Clothes Dry

ThinkstockExcessive underarm sweating is called axillary hyperhidrosis. One clue that you have this sweaty armpit condition is the way you dress. If you don't want to wear light- or bright-colored tops because you're afraid that the stains from your underarm sweating will be too obvious, or you avoid delicate fabrics such as silk because you're afraid they'll get ruined, you're likely dealing with excessive armpit sweat. Men with underarm hyperhidrosis are also likely to keep their suit jackets on, even when it's warm, because they're afraid that people will see the shirt stains around their sweaty armpits.1695

Deodorants Don' t Do Enough to Block Armpit Sweat

ThinkstockAsk your doctor why you sweat so easily. There are good answers. If you're experiencing excessive sweaty armpits, ordinary over-the-counter deodorants won't work, no matter how often you apply them. You may have some success with antiperspirants that have a high concentration of aluminum chloride, which binds to, and therefore blocks, sweat glands, but at times even that isn't enough. Asking your doctor for a prescription-strength antiperspirant to block armpit sweat. Some people who sweat too much have success with prescription antiperspirants, but occasionally further treatment is necessary, notes Jacob DeLaRosa, MD, the chief of cardiac and endovascular surgery at the Idaho State University Portneuf Medical Center in Pocatello.1696

Do You Ruminate About Sweaty Armpits

ThinkstockWhen you have underarm hyperhidrosis, many times it's difficult to think about anything else. You worry that others will notice that your shirt is always soaked. You may become self-conscious and begin to withdraw, avoiding physical contact with other people. You may even be reluctant to dance at parties or work out at the gym for fear it will make your armpit sweat worse.1697

Hyperhidrosis Has Nothing to Do With Good Hygiene

ThinkstockUnderarm hyperhidrosis has nothing to do with hygiene, says Dr. DeLaRosa. Nonetheless, people with hyperhidrosis, particularly armpit sweat, find they soak through their shirts soon after putting them on, so they shower constantly and change their clothes several times a day. This may keep you dry temporarily, but when you have hyperhidrosis, showering frequently, even with strong soaps and shower gels, won't stop the problem. Talking to your doctor or dermatologist about hyperhidrosis treatment will, says DeLaRosa.1698

Medical Management Can Help You Cope With Symptoms of Excessive Sweating

ThinkstockSweating too much is not dangerous or life-threatening, but it's life-limiting if it makes you withdraw and disrupts your daily activities, DeLaRosa says. If you experience any of these signs of hyperhidrosis, such as sweaty armpits, soaking hands, or sloshy shoes, talk to your doctor. You can start with medical management, including prescription antiperspirants, medications, or botulinum toxin type A injections and other procedures. In the most extreme situations, more permanent solutions, like surgery, may help.1699

Excessive Sweaty Armpits Need Medical Treatment

ThinkstockYou expect sweaty armpits when you work out or when you're about to give a big speech in front of a large audience, but if your armpits sweat for no clear reason — a heavy sweat at any time of the day or night — you're likely experiencing symptoms of excessive sweating, or underarm hyperhidrosis.1700

Profusely Sweaty Hands Is Palmar Hyperhidrosis

ThinkstockPeople with underarm hyperhidrosis are also likely to sweat profusely from other parts of the body, such as their hands, feet, and groin — areas where sweat glands are highly concentrated, says Charles Griff, MD, a dermatologist and the medical director of the Dermatology Depot Med Spa in West Palm Beach, Florida. Hyperhidrosis of the palms is known as palmar hyperhidrosis. When you have this condition, you may have difficulty holding a pen or pencil and writing, driving a car, or using a computer keyboard, all because your hands are slippery.1701

Are You Sloshing in Your Sweaty Shoes

ThinkstockSome people with excessive armpit sweat also have plantar hyperhidrosis, which is excessive sweating of the soles of the feet. When your feet sweat too much, your socks and shoes get wet, leaving you feeling as if you've stepped in a puddle. You can become embarrassed about taking off your shoes and socks in public places, like the locker room at the gym or the shoe store, in part because of the ensuing odor. You may have crossed sandals off your wardrobe list because your feet are too slippery, and walking barefoot can be a problem when you're leaving wet footprints behind.
