Main Causes Of Excessive Sweating | What Causes Sweating – SweatBlock

What are the causes of excessive sweating? Unpredictable, profuse sweating can be head scratching. And like some things… there isn’t a one-size-fits-all answer.

Heavy sweating can be caused by overactive sweat glands, genetics, climate, anxiety, or a prescription medication you’re taking.

Excess sweat can also be a symptom of something more serious. In this article we’ll explore the main causes of excessive sweating.

Why Does My Body Sweat So Much?

Producing sweat is how your body regulates your overall body temperature. Basically, any time your body temperature rises, you produce sweat, which helps cool your body down to normal temperature.

Because your body produces sweat any time your internal temperature rises, there are several things that could impact the amount of sweat you produce. Understanding this fundamental process is key to figuring out what causes excessive sweating in your specific situation. These factors include:

Anxiety
Hormone levels
Outside temperatures
Medications
Physical activity

Your body is always sweating — even when you don’t feel it. If you’re lucky, the sweat your body produces evaporates quickly. But if you produce a lot of sweat, it won’t evaporate as it’s produced, and you’ll start to see small droplets on your skin.

You have more than three million sweat glands on your body, so sweat can be produced pretty much anywhere. However, some parts of your body — such as your underarms, the soles of your feet, your groin area, and the palms of your hands — have more sweat glands than other areas. That’s why you might see more sweat production in those areas.

Medical Conditions That Can Cause Excessive Sweating

If you're asking what causes excessive sweating, an underlying medical issue is a possibility that should be considered.

Endocarditis
Diabetic hypoglycemia
Heat exhaustion
Fever of undetermined cause
Hyperthyroidism (overactive thyroid)
Generalized anxiety disorder
Heart attack
Leukemia
Hyperhidrosis
Non-Hodgkin’s lymphoma
Menopause
Stress
Tuberculosis
Obesity

Can Excessive Sweating Be Cured?

While we’d love to tell you there’s a sure-fire cure for excessive sweating, we just can’t. Body chemistry, sweat severity, diet, anxiety levels, and medications can all impact our sweating. While a universal cure is elusive due to the many causes of excessive sweating, effective treatments are available.

However, there are treatments and lifestyle changes that can help you sweat less.

If you sweat a lot, consider a clinical strength antiperspirant. While not a permanent fix, antiperspirants (not deodorants) can provide temporary relief while you explore a longer term solution to your excessive sweating.

If you’ve tried different home remedies and clinical-strength antiperspirants and haven’t found anything that works, you should consider consulting your doctor for advice. In some cases, doctors and/or dermatologists might prescribe an anticholinergic to help reduce the amount of sweat your body produces. This medication is either prescribed in pill or cream form — depending on which part of your body sweats a lot. For excessive head sweating, some dermatologists use botox injections as a treatment. The botulinum toxin freezes the glands in the treated area so they don’t produce sweat.

Beta-blockers (propranolol) and benzodiazepines also may be prescribed if your excessive sweating is a result of anxiety. While these don’t reduce the amount of sweat you produce, they do help control your anxiety levels, which in turn, reduces sweat production.

However, there are treatments and lifestyle changes that can help you sweat less. If you sweat a lot, consider a clinical strength antiperspirant. While not a permanent fix, antiperspirants (not deodorants) can provide temporary relief while you explore a longer-term solution.

Does Sweating Too Much Lead to Dehydration?

You become dehydrated when your body loses more water than you consume. So if you are profusely sweating on a regular basis and you aren’t drinking enough water to replenish the amount your body loses, you could become dehydrated. Normal, non-active people should drink between eight and 12 glasses of water per day. But if you sweat excessively on a regular basis, you should consider increasing your water intake slightly. Even an extra glass or two of water per day could keep you from becoming dehydrated.

What Causes Excessive Sweating on the Head, Neck, and Face?

What Causes Extreme Armpit Sweating?

Excessive underarm sweating is the pits! No one wants to be known at work as the guy or gal with pit stains. Understanding what causes excessive sweating in this area can lead to relief. Like other types, it can be caused by a medical condition, nervousness, medications, or overactive sweat glands. It is important to note that there are more sweat glands on your underarm area. The good news is, with the help of a good antiperspirant, most of the sweat your underarm area produces can be kept at bay.

Will Excessive Sweating Stop After Puberty?

Sometimes excessive sweating is caused by overactive hormones, which is why teenagers, pregnant women, and women in menopause typically sweat more than the average person. The good news is, this also means that if your sweating is caused by overactive hormones, it could stop after puberty. Once the hormones in your body settle down a bit, your body won’t produce as much sweat. In the meantime, consider using a clinical-strength antiperspirant, such as SweatBlock towelettes, to control the amount of sweat our body produces.

Common Health Problems Associated With Excessive Sweating

Medications and Excessive Sweating

If you’ve started a new medication, and then noticed that you’ve started sweating a lot more, the medicine could be the answer to what causes excessive sweating for you. This is one of the most common causes of excessive sweating. The side effect is typically associated with painkillers, antidepressants, cardiovascular drugs, and hormonal drugs.

Antidepressants are one of the most common medications that cause sweating. In fact, about 19 percent of people taking an SSRI or SBRI antidepressant report increased amounts of sweating. So if you’re taking Celexa, Zoloft, Prozac, Paxil, Luvox, Lexapro, or Symbyax, and you’ve started breaking out in sweats, you may want to discuss other options with your doctor.

Even though increased sweat production is a sign of a hormonal imbalance, it can also be caused by the medication you take to balance your hormones out. This includes thyroid regulators, endocrine hormones, testosterone drugs, vasopressins, and certain types of birth control, specifically Depo-Provera.

Excessive sweating is also a side effect of analgesic painkillers such as Vicodin, Methadone, OxyContin, Vioxx, Ultram, Celebrex, and any fentanyl-based drug. While it’s most often associated with withdrawal, these medications can cause you to sweat while you take them. Prescription Midol and Aleve can also cause you to sweat more than normal. The good news is, there are other painkillers available. If one of these options increases the amount of sweat you produce, talk to your doctor about switching to prescription-strength IB Profen, Tylenol, or another non-narcotic painkiller.

When To See a Doctor

Even though hyperhidrosis is annoying and embarrassing, it isn’t a condition that’s medically serious. You should consult your doctor if you are having trouble treating the condition on your own. If you believe the causes of excessive sweating you're experiencing are from a severe medical condition, you should consult your doctor as soon as possible. Your doctor can help you determine what causes excessive sweating and recommend the best course of action.

If you believe that your excessive sweating is caused by a more severe medical condition, you should consult your doctor as soon as possible. If this is the case, you would probably notice all-over body sweating, because it’s more associated with other medical conditions than sweating in one part of your body. Also, there’s a good chance you’ll have other signs of the illness as well. Regardless, no one knows your body the way you do, so if you’re concerned that the excessive sweating you’re experiencing is caused by something more severe, go to the doctor.

If you’re taking medication and you think that medication is causing your excessive sweating, you should also talk to your doctor. You never know, your doctor may be able to suggest a similar medication that doesn’t make you sweat a lot.

The fact is, excessive sweating is always annoying. It can be really embarrassing too. But with a combination of clinical-strength antiperspirants, such as SweatBlock, and your doctor’s recommendations, you can reduce the amount of sweat your body produces.

FAQs

There are two main categories: primary hyperhidrosis and secondary hyperhidrosis. Primary focal hyperhidrosis is the most common type of hyperhidrosis; it is not caused by another medical condition, so there is no known reason for it, though it can run in families. This type is a form of focal hyperhidrosis, meaning it affects specific body parts. In contrast, secondary hyperhidrosis, often referred to as generalized hyperhidrosis, is when the excess sweating is due to an underlying medical cause or as a side effect of certain medications. With this type, the sweating can occur over the entire body or whole body. Finding the underlying cause, such as various health conditions, is key to managing it.

Sweating hyperhidrosis is caused by overactivity of the sympathetic nervous system, which sends faulty signals to your sweat glands. This part of the nervous system triggers the eccrine sweat glands to produce too much sweat even when your body doesn't need cooling. This is the source of hyperhidrosis sweat. While eccrine sweat glands are located all over the skin's surface, they are most concentrated in the hands, feet, face, and underarms. Apocrine glands, which are found near hair follicles, are more associated with causing body odor when sweat mixes with bacteria on the skin. The main symptom is sweating for no apparent reason, such as when you aren't hot or feeling anxious.

To diagnose hyperhidrosis, a doctor will review your medical history and symptoms. You will likely be hyperhidrosis diagnosed if you experience excessive sweating at least once a week without a clear trigger. The specific location helps determine the type; for example, palmar hyperhidrosis affects the hands, which can make simple things like shaking hands difficult. Craniofacial hyperhidrosis involves excessive sweating of the head and face. Once the specific condition affects you is identified, appropriate treatment can be discussed.

There are many treatment options and management options available. Treatment often starts with over the counter or prescription strength antiperspirants. If those don't work, other treatments may be recommended to help reduce sweating. These can include certain medications that affect the nerve signals, or even surgery in severe cases to remove sweat glands or disconnect the nerves. For secondary hyperhidrosis, treating the underlying condition or medical cause is the primary goal. Simple lifestyle adjustments, like using air conditioning, can also help manage symptoms in your daily life. Constant wetness can lead to skin infections, making effective hyperhidrosis treatment important for both comfort and health.
