Hyperhidrosis is a condition in which an individual experiences excessive sweating beyond what is necessary for normal thermoregulation. It can affect any area of the body, but typically affects the palms, soles of the feet, underarms or face.
Definition and Types
Hyperhidrosis is classified as either primary focal hyperhidrosis or secondary generalized hyperhidrosis. Primary focal hyperhidrosis occurs when excessive sweating is localized to certain areas of the body and is not caused by an underlying medical condition. Secondary generalized hyperhidrosis occurs when excessive sweating is caused by an underlying medical condition, such as diabetes or menopause.
Causes
The exact cause of primary focal hyperhidrosis is unknown; however, it has been linked to genetics and overactivity in the sympathetic nervous system. Secondary generalized hyperhidrosis can be caused by a variety of medical conditions, including diabetes, thyroid problems, heart disease, menopause and certain medications.
Treatments
The treatment for hyperhidrosis depends on its severity and type. Non-surgical treatments include muscle relaxing injections, prescription antiperspirants, nerve-blocking medications and antidepressants. Surgical treatments include endoscopic thoracic sympathectomy (ETS) and liposuction for axillary hyperhidrosis.
Diagnosis based on severity of sweating, physical examination, medical tests, and skin biopsy.
Diagnosis
Symptoms and Severity
Hyperhidrosis is usually diagnosed based on the severity of sweating and the areas affected. In some cases, a physical examination may be done to check for any signs of excessive sweating. The doctor may also ask questions about the patient’s medical history and lifestyle to determine if there are any underlying causes that could be contributing to the symptoms.
Medical Tests
In some cases, additional tests may be needed to rule out other conditions or diseases that could be causing similar symptoms. These tests can include blood tests, urine tests, sweat tests, and imaging scans such as X-rays or CT scans. In some cases, a skin biopsy may also be done to check for any underlying skin disorders that could be causing excessive sweating. Once all of these tests have been completed, the doctor will then make a diagnosis based on the results.
Non-surgical treatments for hyperhidrosis include muscle relaxing injections, prescription antiperspirants, nerve blocking medications, and antidepressants.
Non-Surgical Treatments
Hyperhidrosis can be treated without surgery. Non-surgical treatments are the first line of treatment for excessive sweating, as they are less invasive and require less recovery time than surgical treatments.
Muscle Relaxing Injections
Muscle relaxing injections, such as Botox or Dysport, are a common non-surgical treatment for hyperhidrosis. The injection is used to temporarily paralyze the sweat glands in the area where it is injected, preventing them from producing sweat. The effects of these injections usually last for six to nine months before additional injections are needed.
Prescription Antiperspirants
Prescription antiperspirants contain higher concentrations of active ingredients than those found in over-the-counter products. These antiperspirants are applied to the affected area at night and washed off in the morning. They work by blocking sweat glands and preventing them from producing sweat.
Nerve Blocking Medications
Nerve blocking medications, such as glycopyrrolate, can be used to reduce sweating by blocking signals from the nerves that control sweating. These medications must be taken orally on a daily basis and can take several weeks to take effect.
Antidepressants
Antidepressants can also be used to treat hyperhidrosis. This type of medication works by decreasing nerve activity that causes excessive sweating. However, this type of medication is not recommended for long-term use due to potential side effects.
In summary, non-surgical treatments for hyperhidrosis include muscle relaxing injections, prescription antiperspirants, nerve blocking medications, and antidepressants. While these treatments may provide relief from excessive sweating in some cases, they may not be effective in all cases and may need to be combined with other forms of treatment such as lifestyle changes or surgical treatments.
Surgical Treatments
Surgical treatments are considered when other non-surgical treatments have not been effective in controlling the symptoms of hyperhidrosis. These procedures are generally more invasive and can be costly, but they offer a more permanent solution for those who suffer from severe cases of excessive sweating.
Endoscopic Thoracic Sympathectomy (ETS)
Endoscopic thoracic sympathectomy (ETS) is a surgical procedure that involves cutting or clipping the nerves responsible for controlling sweat production. This procedure is performed under general anesthesia, and requires a small incision to be made in the chest area to access the sympathetic nerves. The surgeon then uses an endoscope, which is a thin tube with a camera on the end, to locate and clip the nerves. After the surgery, patients may experience some side effects such as compensatory sweating, which is when sweat production increases in other areas of the body to compensate for sweat reduction in treated areas.
Liposuction for Axillary Hyperhidrosis
Liposuction for axillary hyperhidrosis is another surgical option that involves removing fat from the armpit area to reduce sweat production. During this procedure, a small incision is made near the armpit and a thin tube called a cannula is inserted into the area to suction out excess fat cells. This procedure does not require general anesthesia and can usually be completed within an hour. Patients may experience some swelling and bruising after this surgery, but these should resolve within a few days.
Overall, surgical treatments can provide long-term relief from hyperhidrosis symptoms for those who have not found success with non-surgical treatments. However, it is important to discuss all potential risks and benefits with your doctor before deciding if surgery is right for you.
