Hyperhidrosis is abnormally excessive sweating that’s not necessarily related to heat or exercise. You may sweat so much that it soaks through your clothes or drips off your hands. Besides disrupting normal daily activities, this type of heavy sweating can cause social anxiety and embarrassment. If antiperspirants don’t help, you may need to try different medications and therapies.
Most people sweat when they exercise or exert themselves, are in a hot environment, or are anxious or under stress. The excessive sweating experienced with hyperhidrosis far exceeds such normal sweating. The type of hyperhidrosis that usually affects the hands, feet, underarms or face causes at least one episode a week, during waking hours. And the sweating usually occurs on both sides of the body.
Sweating is your body’s mechanism to cool itself. Your nervous system automatically triggers your sweat glands when your body temperature rises. Sweating also normally occurs, especially on your palms, when you’re nervous. The most common form of hyperhidrosis is called primary focal (essential) hyperhidrosis. With this type, the nerves responsible for signalling your sweat glands become overactive, even though they haven’t been triggered by physical activity or a rise in temperature. With stress or ervousness, the problem becomes even worse. This type usually affects your palms and soles and sometimes your face.
There is no medical cause for this type of hyperhidrosis. It may have a hereditary component, because it sometimes runs in families.
Secondary hyperhidrosis occurs when excess sweating is due to a medical condition. It’s the less common type. It’s more likely to cause sweating all over your body. Conditions that may lead to heavy sweating include:
- Menopause hot flashes
- Thyroid problems
- Low blood sugar
- Some types of cancer
- Heart attack
- Nervous system
Certain medications also can lead to heavy sweating, as can opioid withdrawal.
Complications of hyperhidrosis include: Infections. People who sweat profusely are more prone to skin infections. Social and emotional effects. Having clammy or dripping ands and perspiration-soaked clothes can be embarrassing. Your condition may affect your pursuit of work and educational goals.
Our practitioners will advise you if you are an appropriate candidate for Botox injections for hyperhidrosis. Botox injections use botulinum toxin to block the nerve signals responsible for sweating, stopping the sweat glands from producing too much sweat. In some cases our practitioners may also advise to use prescription strength antiperspirants
Injecting Botulinum Toxin can help sufferers of excessive sweating by limiting the glands ability to produce sweat. The treatment can reduce hyperhidrosis by up to 90%. The nerve-blocking injections are suitable for all areas of the body, including the hands. Results can be experienced within as little as three days, with effects last up to nine months.
Botox injections use botulinum toxin to block the nerve signals responsible for sweating, stopping the sweat glands from producing too much sweat. Retreatment is typically needed in four to six months, as the nerves regenerate. Over time, however, patients can go longer between treatments.
The underarms, in particular, respond well. Sweat glands on the hands and feet also respond well to Botox injections, but patients tend to find the injections themselves more painful on the hands and feet because there are more nerve endings there. We always offer numbing cream to make our clients more comfortable.
The effects of Botox are temporary, which means you’ll need more injections in the future. For underarm sweating, dryness can last anywhere from four to fourteen months. Results may not last as long for the hands and feet, and you may need to repeat your treatment in about six months.
Botox takes approximately 5-20 minutes. For other techniques, the treatment time may be longer.
Results can be experienced within as little as three days.
