When excessive sweating is the main complaint and is not related to any other condition, it is called primary hyperhidrosis. There is no known cause, but it does tend to run in families. Secondary hyperhidrosis is sweating that is caused by another medical condition, such as anxiety, cancer, hyperthyroidism, or menopause. Sometimes treating the underlying condition can improve this type of sweating.

There are tests doctors can use to diagnose hyperhidrosis. One involves simply soaking up the perspiration with paper and then weighing the paper to measure how much extra sweat is being produced. Another test, called the starch-iodine test, involves covering the body with powder. This powder turns blue in any areas where sweat is produced.

Treatment depends on the severity of the hyperhidrosis and the areas affected. Some options are:

• Prescription antiperspirants, which contain aluminum chloride and work by plugging the sweat ducts. This signals the sweat glands to decrease sweat production. They work for moderate cases of hyperhidrosis and are relatively affordable.
• Lontophoresis, a procedure that uses small amounts of electricity and a tray of tap water to decrease production of sweat glands in the hands or feet.
• Botox, which can be injected into the nerves that control sweat glands in the underarms.
• Sympathectomy, a surgery for severe cases that can be performed to cut the nerves that stimulate sweat production. Sympathectomy is most effective for hyperhidrosis of the hands. It may cause new symptoms of sweating elsewhere on the body.
• Surgery to remove sweat glands, most often in the underarms.

Hyperhidrosis is a serious medical condition that causes both physical and emotional distress. Treatments are available, and support groups exist to help patients cope.

During surgery, the blockage is identified, and an incision is made to expose the artery. The surgeon prepares a tube, called a graft, to be used as the bypass. Sometimes this tube is synthetic, and sometimes a piece of the patient's own vein or artery is used. The ends of the bypass graft are attached to the artery above and below the blockage. Now blood can simply flow around and continue on its way.

After a peripheral bypass, patients may need to spend a couple of days in the hospital while doctors make sure the bypass is working and not leaking. If the bypass was done in the leg, doctors may check the pulse in the feet to make sure blood is flowing well. Patients may experience some swelling in the area where they had surgery. Raising an arm or leg will help. Patients will likely be back to normal activities within 2-3 weeks.

Both hypothyroidism and goiters are caused by an autoimmune reaction where the body produces antibodies that attack the thyroid cells for unknown reasons. The thyroid reacts by releasing too little or too much T3 and T4 thyroid hormones, impairing thyroid function and causing irregular metabolism. Goiters develop from the autoimmune reaction causing continued antibody damage to the thyroid over time. Thyroid goiters are large, swollen lumps that can be felt near the base of the neck. Obstructive goiters can cause pain, coughing, and abnormal breathing. Hypothyroidism may also be caused by iodine deficiency, as iodine is needed to produce thyroid hormones.

The exact cause of thyroid cancer and thyroid nodules or cysts is unknown. While thyroid cancer and thyroid nodules or cysts can occur in individuals with thyroid disorders, they are not associated with a malfunctioning thyroid.

Physicians may prescribe thyroid surgery if blood tests reveal patients' thyroid stimulating hormones (TSA) are outside of the acceptable range, indicating a malfunctioning thyroid. Thyroid biopsies (tissue samples) and tests for thyroid-attacking antibodies are also criteria for surgery.

An ENT or general surgeon performs thyroid surgery. While a patient is placed under anesthesia, the surgeon makes an incision at the center of the neck and removes the thyroid gland. Two alternative methods of thyroid surgery are transoral (incision through the mouth) and endoscopic, where a surgeon operates a video camera for live footage to help guide the removal process.

Thyroid surgery requires minimal aftercare. Most patients recover quickly and resume normal activities within a few days of surgery. However, thyroid surgery patients must take daily synthetic thyroid medication (levothyroxine) for life to replace their removed thyroid.
