Why Do My Armpits Smell Like Onions?
For most of us, sweat is a normal part of everyday life. It’s common to smell after a tough workout or on a hot day. But did you know that it’s actually bacteria mixing with sweat on your skin that causes body odor, not the sweat itself? So, why do your armpits sometimes smell like onions? Here are four reasons, according to dermatologist Azadeh Shirazi, MD, FAAD, and how to combat it.
1. Hormonal Fluctuations:
Changes in hormones can affect body odor. For example, you may notice a different scent during your menstrual cycle or when you’re pregnant due to hormonal shifts. Menopause and high stress can also lead to changes in body odor.
2. Underlying Health Conditions:
If your body odor suddenly smells like onions, it could be a sign of an underlying health issue like hyperhidrosis or conditions like diabetes, an overactive thyroid, or liver problems. Bromhidrosis, a condition where bacteria breaks down sweat and causes a strong odor, can also be a culprit.
3. Diet:
What you eat can impact body odor. Foods like garlic, onions, red meat, and certain spices can change the way you smell. Chemicals in food can increase bacteria, leading to a stronger odor.
4. Aging:
As we get older, our body odor can change due to increased levels of certain chemical compounds, such as 2-nonenal, which causes a musty smell. Hygiene practices can help mitigate this odor.
How to Get Rid of Onion-Smelling Armpits
If you’re concerned about your body odor, here are some tips to help combat it:
1. Apply Deodorant:
Choose a deodorant or antiperspirant to mask odors and reduce sweat. Antiperspirants contain aluminum salts that block sweat production.
2. Try Home Remedies or Lifestyle Changes:
Home remedies like baking soda or green tea bags can help reduce body odor. Lifestyle habits, such as keeping armpit hair trimmed and wearing breathable clothing, can also make a difference.
3. Consult a Dermatologist:
Your dermatologist can recommend products like glycolic acid pads to reduce odor-causing bacteria. Prescription-strength antiperspirants or Botox injections may also be options for controlling excessive sweating.
Overall, if over-the-counter measures are not working, it’s a good idea to see your doctor to rule out any underlying health issues that may be causing your body odor.
