why do my underarms sweat so much

Change your diet. Strong-smelling foods and some food families will affect the way your sweat smells, according to recent studies. If you already tend toward sweatiness, it's important to be aware of dietary issues that might be making it worse. Onions, garlic, and other foods in the alliaceous family will cause sulfurous, pungent sweat upon drying. Some spices, like asafetida, cumin, and curry powder will likewise be detectable in the underarms, as well as cruciferous vegetables like cabbage or broccoli. Diets high in red meat, dairy, or alcohol produce distinctive-smelling sweat that many people become acclimated to over time. Capsaicin, found in hot peppers, will stimulate the nerve receptors in your mouth in the same way that actual heat does, tricking your body into thinking that you're hot. Your hypothalamus will send out a signal to sweat.
Excessive underarm sweating is an embarrassing problem, leading to stained clothing, body odor, anxiety and even social isolation.


In some cases, underarm sweating is easily controlled with the correct application and use of antiperspirants. However, if the excessive sweating is an ongoing problem which has affected you for more than 6 months, your doctor may use the term hyperhidrosis -- which may require different options. If over-the-counter antiperspirants won't control the sweat, your doctor can address other treatments, including prescription antiperspirant or medications, Botox injections or other procedures or surgery to reduce or stop sweating. While deodorants help control the odor associated with underarm sweating, they do not reduce or stop sweating. Make sure your underarm product is an antiperspirant, and if preferred, also a deodorant.


Antiperspirants stop sweating by temporarily blocking the sweat glands in the underarms, which prompts your body to reduce or stop the flow of sweat. Make sure you are using the product correctly. The American Academy of Dermatology recommends antiperspirants be applied to dry skin -- at night. Because most people sweat less at night, applying the underarm product before bed allows the active ingredients to plug the pores and stop underarm sweating before you wake up in the morning. Even if the antiperspirant washes off with morning bathing, these active ingredients work for at least 24 hours. If your antiperspirant is not doing its job to stop sweating, try a clinical strength product. These products contain a higher amount of the active ingredient, which is usually an aluminum-based compound.


If this doesnвt work, ask your doctor if you can try a prescription antiperspirant. Follow the directions on use, as these stronger products can lead to more skin irritation. Wear clothing made of natural fibers, such as cotton or silk, to improve air circulation and keep your skin dry. When exercising, choose synthetic fabrics that are designed to wick moisture away from your skin and reduce sweating and odor. Also consider using underarm liners or absorbent or sweatproof undershirts, which are made to absorb sweat. If you are still not getting sweat relief, talk to your doctor about other options. Botox injections can control excessive sweating for several months by blocking the chemical that activates the sweat glands. A relatively new, noninvasive microwave technology is also available which causes localized destruction of sweat glands, offering a permanent solution.


If these treatments donвt work, your doctor can prescribe medications that temporarily prevent sweating, or less commonly perform surgery that either removes sweat glands or targets the nerves that control sweating. Underarm liners, absorbent or sweatproof undershirts Keep a sweat journal, noting the situations and conditions that prompt you to sweat more. You may find that anxiety, heat and even certain foods trigger your sweating. Discuss your findings with your doctor. Excessive sweating can be a frustrating problem, and cause significant stress and anxiety for anyone affected. Ask your doctor for a referral to a dermatologist. This specialist will be aware of the variety of treatment options available to help you manage this condition.
