Millions of people suffer from primary hyperhidrosis (excessive sweating) which has no known cause or cure. But if you’re part of a smaller pool of people, your excessive sweating can be traced back to the source - and potentially reversed.

Known as secondary hyperhidrosis, this type of excessive sweating is a side effect of a medication or medical condition and generally starts in adulthood. People with secondary hyperhidrosis also sweat while sleeping, which does not occur in cases of primary hyperhidrosis.

Excessive sweating doesn’t have to dictate your everyday life. By identifying the root cause of secondary hyperidrosis, you can better manage (and potentially eliminate) it.

If you’re unsure whether a medication or medical condition is prompting your heavy sweating, consider these common causes of secondary hyperhidrosis.

1. Medical Conditions

Many medical conditions have been linked to excessive sweating, including:

  • Anxiety and depression
  • Cancer
  • Alcoholism
  • Obesity
  • Heart and lung disease
  • Stroke
  • Tuberculosis and other chronic infections

If you’ve recently been diagnosed with one of these conditions (or could be at risk), your sweating may come with the territory. In any case, it’s best to consult a doctor.

2. Pregnancy and Menopause

Hormonal changes that occur during pregnancy and menopause can trigger hot flashes and night sweats. The extra weight a baby adds and increased blood flow also contribute to heavy perspiration.

3. Medications

Sweating is also a side effect of certain drugs, including:

  • Antidepressants
  • Nonsteroidal anti-inflammatory drugs
  • Blood pressure medications
  • Cancer treatments
  • Diabetes drugs

4. Weight Gain 

Everyone responds to temperature or exercise differently. It’s why some people run for a minute before the sweat starts pouring and others can go 30 minutes and barely break a sweat.

When carrying extra weight, your body is forced to work harder during everyday activities, so you could see heavy sweating as a result of weight gain. More weight also tells your body you need more sweat to cool down.

Your Secondary Hyperhidrosis Checklist

If you’re still unsure whether a medication or medical condition is causing your excessive sweating, here are some signs that could be the case:

  • Your symptoms started after age 25.
  • Heavy sweating doesn't run in your family.
  • You recently started taking a medication listed above or were diagnosed with a medical condition that may cause sweating.
  • Sweating occurs everywhere, not in one particular area.
  • You also experience flu-like symptoms such as fatigue and headaches.
  • You sweat heavily when sleeping.
  • You are approaching the age of menopause or may be pregnant. 

While secondary hyperhidrosis can be reversed, forgoing certain medications you rely on could pose greater health risks. It’s always wise to consult your doctor before making any health-related decisions.
