When we discuss hyperhidrosis, the medical term for excessive sweating, many people envision it starting in the teenage years. And for some, that’s true. Primary hyperhidrosis begins in childhood or adolescence, particularly affecting the hands, feet, underarms, or face.
But what if you start sweating more in your 30s, 40s, or beyond? Is it still hyperhidrosis? Can it begin later in life? And when should you be concerned?
Let’s explore what later-onset hyperhidrosis means, its causes, and how to manage it.
Understanding the Two Types of Hyperhidrosis
There are two main types of hyperhidrosis:
- Primary hyperhidrosis is a chronic condition characterised by excessive sweating, whatever the weather, that occurs without an underlying medical cause. It typically begins in childhood or adolescence and tends to affect specific areas, such as the hands, feet, underarms, or face. It's symmetrical (both sides of the body are affected) and is made worse by stress, heat, or no apparent reason at all.
- Secondary hyperhidrosis, on the other hand, is caused by another medical condition or as a side effect of medication. This type of hyperhidrosis can start at any age, and it's the most common reason people develop excessive sweating later in life.
Yes, You Can Develop Hyperhidrosis Later in Life
If you suddenly notice you’re sweating more than usual, especially if it's all over your body or happening at night, it’s worth speaking to a healthcare professional. While it may not always be serious, late-onset excessive sweating is often a symptom of an underlying condition.
Possible causes include:
- Menopause/Perimenopause: Hormonal changes can trigger hot flushes and night sweats, often mistaken for hyperhidrosis. But for some, the sweating is severe and persistent.
- Thyroid issues: An overactive thyroid (hyperthyroidism) can increase metabolism and lead to excessive sweating.
- Infections: Most viral or bacterial infections can cause temporary sweating.
- Diabetes: Low blood sugar (hypoglycaemia) and other diabetic complications can result in sweating or gustarory sweating (sweating when you smell or taste food).
- Medications: Antidepressants, painkillers, and some diabetes or hormone treatments can list sweating as a side effect.
- Anxiety or stress disorders: These can trigger physical symptoms, including sweating, particularly on the face, chest, and back.
- Other underlying conditions: Cancers, neurological conditions (such as Parkinson’s disease), and heart problems can occasionally lead to secondary hyperhidrosis.
If your sweating starts suddenly, worsens over time, or is accompanied by other symptoms (such as weight loss, fatigue, or fever), it’s essential to rule out medical causes first.
What Should You Do?
If you suspect you’ve developed hyperhidrosis later in life, your first step should be to speak with your GP. They may carry out blood tests or refer you for further investigations to determine whether there’s an underlying cause.
Keeping a symptom diary can also be helpful; note when the sweating occurs, how long it lasts, and whether anything triggers or relieves it.
Once other causes are ruled out, you may be diagnosed with idiopathic secondary hyperhidrosis (meaning there's no clear cause), or you may be treated for the underlying condition if one is found.
How to Manage Later-Onset Hyperhidrosis
Regardless of the cause, excessive sweating can significantly impact your daily life, confidence, and overall comfort. Thankfully, there are effective ways to manage it.
Some options include:
- Clinical-strength antiperspirants: These are stronger than shop-bought versions and can be used on many parts of the body.
- Iontophoresis: A great option for hands and feet, this treatment uses a mild electrical current to reduce sweat production over time.
- Prescription medication: Some oral treatments can help reduce overall sweating but usually have many unwanted effects including dry mouth and constipation.
- Lifestyle changes: Breathable clothing, skincare routines, and cooling techniques can make a big difference day to day.
