Causes of Secondary Hyperhidrosis: Can Your Heavy Sweating Be Reversed?

Millions of people suffer from primary hyperhidrosis (excessive sweating), which has no known cause or cure. However, there is a specialized type of  hyperhidrosis can be traced back to a source — and potentially reversed.

Where primary hyperhidrosis typically occurs in specific areas, secondary hyperhidrosis causes sweating all over the body. Causes of secondary hyperhidrosis include certain medical conditions, pregnancy, menopause, medication side effects and weight gain. 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 causes of secondary hyperhidrosis, you can better manage (and potentially eliminate) it.

Causes of Secondary Hyperhidrosis

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
  • Infectious diseases, including tuberculosis and HIV
  • Spinal cord injuries
  • Parkinson’s disease

If you’ve recently been diagnosed with one of these conditions (or could be at risk), your sweating may come with the territory.

2. Pregnancy and Menopause

Hormonal changes that occur during pregnancy and menopause can trigger hot flashes and night sweats. The extra weight of carrying a baby and increased blood flow also contribute to heavy sweating across the entire body.

For pregnant women, excessive sweating only lasts the duration of the pregnancy. For women going through menopause, the length of secondary hyperhidrosis symptoms varies. Some women experience hot flashes for a few months, while others have them for up to a decade.

3. Medications

Certain drugs can also cause secondary hyperhidrosis. The list of sweat-causing drugs includes:

  • Antidepressants such as Protriptyline and Nortriptyline
  • Nonsteroidal anti-inflammatory drugs
  • Blood pressure medications
  • Cancer treatments
  • Diabetes drugs
  • Pilocarpine, a drug that prevents dry mouth

Even simple dietary supplements can cause excessive sweating. These include:

  • Zinc supplements
  • Iron supplements

4. Weight Gain

Everyone responds to temperature and exercise differently. It’s why some people only last a few minutes on a run before they’re dripping with perspiration, while others can run for 30 minutes and barely break a sweat.

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

Your Secondary Hyperhidrosis Symptom Checklist

If you’re still unsure what is causing you to sweat excessively, here are some telltale signs that you have secondary hyperhidrosis:

  • 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.

The good news is that secondary hyperhidrosis can be reversed. But 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.
