Excessive sweating, medically known as Hyperhidrosis, is a condition that can affect either the entire body or specific areas such as the palms, underarms and feet. While sweating is a normal response to heat or physical activity, hyperhidrosis occurs without an obvious need for the body to cool down.
According to the UK’s National Health Service, the condition may improve over time, but in many cases it requires active management.
What causes excessive sweating
Hyperhidrosis can appear without a clear trigger, but it may also be linked to underlying medical conditions or occur as a side effect of medication.
In such cases, identifying the cause is key to determining the appropriate treatment approach.
Simple adjustments in daily routine can reduce the impact of sweating:
- Wearing loose-fitting clothing can minimise visible sweat marks
- Choosing moisture-absorbing socks and changing them regularly can help manage foot perspiration
- Opting for breathable footwear, such as leather shoes, and rotating pairs daily can improve comfort
Certain triggers are known to worsen sweating and should be limited where possible. These include alcohol and spicy foods.
Tight clothing and synthetic fabrics, such as nylon, can also increase perspiration and should be avoided.
Support from pharmacies
Pharmacists can offer over-the-counter solutions to help manage symptoms. These include stronger antiperspirants, underarm pads to protect clothing, foot powders and mild cleansers designed for sensitive skin.
When to seek medical advice
Medical consultation is recommended when symptoms persist or interfere with daily life. According to the NHS, individuals should consider seeing a doctor if:
- lifestyle changes do not improve symptoms
- sweating continues for more than six months
- it affects everyday activities
- it occurs at least once a week
- it happens during sleep
- there is a family history of the condition
- medication may be contributing to the symptoms
A doctor may recommend further tests if an underlying cause is suspected.
Treatment options for persistent cases
For more severe or long-term cases, referral to a specialist may be required. Available treatments include medication to reduce sweating, iontophoresis, which uses a mild electrical current, and injections such as botulinum toxin for targeted areas like the underarms.
In certain cases, surgical options, including the removal of sweat glands, may be considered.
Management depends on whether hyperhidrosis is a primary condition or linked to another health issue, in which case treatment focuses on the underlying cause.
