10 Conditions That Make People Sweat Too Much

Botox: For the image-conscious and super sweaty individual.

Hyperhidrosis is just a fancy way of saying too much sweat. The 2-3 percent of the population with this condition sweat a lot more than usual, and do so somewhat unpredictably – that is, not necessarily when they are hot or exercising [source: Medline Plus]. This excess sweating can lead, not just to discomfort of excess wetness and increased risk of fungal infections and skin conditions, but emotional stress as well.

While doctors aren't sure of the causes of this condition -- other than noting that it seems to run in families -- they do have several ways to treat it. Some treatments are milder, like heavy-duty antiperspirant or medications that prevent the stimulation of sweat glands. Other treatments are out there, too, like Botox, which temporarily blocks the nerves that stimulate sweating, or iontophoresis, which uses a gentle electrical current to temporarily turn off sweat glands.

Both of these solutions, while generally helpful, are temporary and need continued treatments to remain effective. For patients who don't respond to any of these treatments, there's always the option of surgery to either remove some sweat glands directly or another surgery called a sympathectomy in which a surgeon cuts or destroys certain nerves in an attempt to turn off the signal that tells the body to sweat excessively.

Doctors will call the same type of excess sweating secondary hyperhidrosis if the sweating happens as a result of another condition. As it happens, we can tell you about a few of those, too.

Of course menopause made this list.

Hot flashes and night sweats -- two of the signs that a woman is going through menopause. If you're a guy and won't ever experience this joy for yourself, you've most certainly seen a close female friend or family member get flushed and sweaty for seemingly no reason at all.

Well, there is a good reason for this excess sweating. Hormones. Women's bodies are being altered rapidly in unseen ways, courtesy of unpredictable changes in hormone production by their ovaries, the two main culprit hormones being estrogen and progesterone. These chemical substances travel through the blood to other parts of the body and can control how cells work. For example, estrogen can affect the cells in your blood vessels, causing them to expand. So during a hot flash, women's faces and upper bodies get red and flushed thanks to these blood vessels expanding. The result is excessive heat and, oftentimes, excessive sweating several times an hour, a few times a day, or maybe as little as a couple times a week.

The thyroid may be a little gland, but don't underestimate its power over the body.

Hormones strike again. This time they're causing excess sweating because of the thyroid gland overdoing it on the production of thyroid hormone, a condition known as hyperthyroidism. This little gland is nestled right under our voice boxes in our necks and is responsible for making thyroid hormones that affect a number of bodily processes including metabolism, brain development, breathing, weight and body temperature.

What happens when your thyroid goes wacky and produces too much thyroid hormone? Your body temperature is affected, your heat intolerance rises, and you start sweating more than normal. While sometimes very severe, hyperthyroidism is treatable with medications and/or surgery, and sometimes can even go away without treatment at all.

Chest pains are certainly one well-known sign of an impending heart attack, but did you know that excessive sweating may be another?

It's not that hot out, but you find yourself sweating profusely. Not to overdramatize this situation (I mean, maybe you had some spicy kung pao chicken for lunch), but excess sweating could be a warning sign of heart failure in men and women.

Heart attack victims are often known to sweat a lot just before and during a heart attack. A major portion of the body's nervous system, the sympathetic nervous system, controls sweating throughout our bodies. When a heart attack kicks in, the sympathetic nervous system gets activated, causing the sweat to pour out.

It’s not necessarily just the cancer that can make you sweat. The treatments associated with this chronic disease can be sweat-inducing, too.

While there are obviously much more terrible things associated with having cancer, sweating is on the list of symptoms with this disease. Doctors don't fully understand why this is but theorize that the sweating may be associated with the body trying to fight the cancer. Some types of cancer cause sweating more than others, including bone cancer, liver cancer, leukemia and lymphoma [source: Cancer Research UK].

It's not always the cancer itself causing excess perspiration. The sweating can be a secondary symptom associated with cancer medications, infections associated with the disease and hormone changes. Morphine and chemotherapy can cause patients to get hot flashes and sweat. Infections are probably one of the most common reason for cancer-induced sweating. The fevers that come with infections cause the body to try to cool itself, kicking those sweat glands into high gear.

And just like hormone changes in menopause and hyperthyroidism can cause sweating, hormone changes associated with cancer and its treatments (chemo, radiation and others) can bring on serious perspiration. In fact, certain treatments for breast and prostate cancer can actually induce menopause or menopause-like effects causing hot flashes and sweating.

Night sweats are the worst.

Infectious diseases like AIDS, malaria and tuberculosis have all sorts of terrible symptoms. Left untreated or at their most severe, they can cause death. With that in mind, sweating seems like, well, nothing to sweat about.

But this uncomfortable symptom can certainly make people with these diseases feel much worse. Night sweats are all quite common with each of these ailments. Patients will wake up drenched in sweat as a result of a severe hot flash, often associated with fever and infection from these diseases.

Now, these are all infectious diseases that can be transmitted from person to person. But not to fear, shaking someone's sweaty palm is not going to spread any of these diseases.

A panic attack can present a lot like a heart attack.

Each year, one in 20 Americans will be diagnosed with panic disorder [source: National Alliance on Mental Illness]. That means millions of people every year experience repeated attacks of fear in response to ordinary situations. What's that like? Severe panic attacks can actually look a lot like heart attacks: pounding heart, dizziness, chest pain, and ... you guessed it, sweating. That same sympathetic nervous system that gets activated during a heart attack and makes you sweat does the exact same thing to your body during a panic attack.

Given that panic disorder causes attacks that come out of the blue, people with the condition live in continual fear of an impending attack. But some sweat-inducing panic attacks do come from a direct cause. We'll tell you about those in a second.

Scared of heights? This situation might make you perspire. Heavily.

Spiders. Airplanes. Heights. You may not even bat an eyelash reading those words, but some people freak out just thinking about these phobia-inducing subjects. And not just some people; about 19 million adult Americans have specific phobias to a variety of objects or situations [source: National Institute of Mental Health].

While panic disorder causes panic attacks in people for no identifiable reason, phobias are another type of anxiety disorder that elicits symptoms of panic attacks due to an intense fear of something specific that poses little to no danger.

And what happens when a person with a phobia encounters the object of their dread? The fear of the object or situation starts in the brain but quickly affects other parts of human physiology. Heart rate increases. Blood pressure ratchets up. And the sympathetic nervous system goes into highly active mode, which, of course, translates into what we've been talking about this whole time: excess sweat.

Partaking of some red hot chili peppers could generate an interesting bodily response.

Picture it: sitting down to a relaxing dinner of spicy tacos and a margarita, followed by an after-dinner coffee. Sounds lovely. That is, until you break out in a profuse sweat. All three of these food and beverages can cause excess perspiration.

Spicy food excites receptors, actually pain fibers, in the skin that respond to heat. When these pain fibers are triggered by the spice-causing chemicals in foods like chili peppers, the central nervous system gets tricked into perceiving the stimulus as heat. The body, as a result, acts accordingly to cool itself down using its natural mechanism of sweat.

Drinking alcohol can also leave you wishing you'd put on extra deodorant. Alcohol causes blood vessels near the skin to enlarge, prompting your sweat glands to start working. This can happen for a lot of people, but when the sweating seems excessive proportional to the amount of alcohol consumed, it is often a sign of alcohol intolerance, where people lack a special enzyme that breaks down alcohol.

And finally, caffeinated drinks and foods can also cause excess sweating. The caffeine molecule stimulates the central nervous system, causing your sweat glands to get activated. And before you know it, you're reaching for a towel to wipe excess sweat from your forehead.

In a total paradox, drinking alcohol can make you sweat, but stopping your consumption of it can also make you perspire extra. We'll tell you why next.

Alcohol: Either way it's going to make you sweat.

Sweating is a classic sign of withdrawal. When people become physically dependent on substances like alcohol and opiate drugs (heroin, morphine, Oxycontin and others) and then stop taking these substances, the body takes a while to recalibrate to its normal operation. And that's when withdrawal symptoms, like excess sweating, kick in.

It's ironic how drinking alcohol makes you sweat, but then stopping your alcohol consumption after becoming dependent on it can make the sweating even worse. Never fear. While incredibly uncomfortable, it's temporary. Some medications are available to help, but the symptoms will eventually go away on their own. Depending on the severity of the withdrawal, it can take weeks for symptoms to subside.
