Here’s Why Your Armpits Smell Even After Applying Deodorant

We rely on deodorant to keep body odor at bay, but sometimes, even after applying it, our armpits fail the sniff test. Wondering why you still smell despite your best efforts? Persistent body odor can result from various factors, ranging from lifestyle choices to underlying health conditions.

Let’s break down the reasons behind those stubborn smells and explore solutions to keep your armpits fresh.

Why Do Armpits Smell?

Body odor primarily originates when sweat interacts with bacteria on your skin. While sweat itself is odorless, the apocrine glands in your armpits produce a thicker, milky fluid that, when broken down by bacteria, emits a strong scent.

1. Hormonal Changes

Hormonal shifts, such as those during puberty or menopause, can increase sweating and alter body odor. For instance:

• Puberty: Activated apocrine glands amplify body odor due to increased sweat production.

• Menopause: Decreased estrogen levels can cause hot flashes and excessive sweating.

Solution: Hormonal fluctuations are usually temporary. If over-the-counter deodorants don’t suffice, consult your doctor for prescription-strength options.

2. Certain Medications

Some medications, including antidepressants (e.g., Prozac, Zoloft, Wellbutrin), penicillin, and dupilumab, can increase sweating and contribute to odor.

Solution: Speak with your healthcare provider if you suspect a medication is causing body odor. They may recommend alternatives, but always consult your doctor before stopping any medication.

3. Skin Conditions

Conditions like intertrigo can lead to redness, inflammation, and unpleasant odors in areas like the armpits. This occurs when heat, moisture, and friction create an environment for bacteria and fungi to thrive.

Solution: If you notice a rash or persistent odor, see a doctor. Treatment may include antifungal or antibacterial medications.

4. Hyperhidrosis

Hyperhidrosis, characterized by excessive sweating, can exacerbate body odor by providing bacteria with more sweat to break down. This condition may also signal underlying health issues like diabetes or thyroid disorders.

Solution: Treatments for hyperhidrosis include antiperspirants, Botox injections, topical medications, or, in severe cases, surgery to block or remove sweat glands. Managing the underlying condition is essential.

5. Underlying Medical Conditions

Rare metabolic disorders like trimethylaminuria (causing a fishy odor) or infections can result in persistent body odor.

Solution: Treating the root cause is critical. For trimethylaminuria, dietary adjustments avoiding foods like choline-rich eggs and fish can reduce odors.

6. Diet

Your diet can influence your body odor. Foods like garlic, onions, broccoli, and cabbage contain sulfur compounds that are released through sweat. Spicy dishes, curry, asparagus, and alcohol can also contribute to offensive smells.

Solution: Limit consumption of odor-inducing foods if you notice a pattern.

How to Keep Armpit Odor Under Control

Try these strategies to reduce body odor:

• Bathe Daily: Use antibacterial soap to remove odor-causing bacteria. Products with benzoyl peroxide can help but may cause irritation for some.

• Choose the Right Products: Opt for a combination antiperspirant and deodorant to prevent sweat and neutralize odors.

• Wear Breathable Fabrics: Materials like cotton and moisture-wicking fabrics help reduce sweat accumulation.

• Shave Regularly: Shaving underarm hair helps sweat evaporate more quickly, minimizing odor.

• Stay Dry: Pat your skin dry thoroughly after bathing to prevent bacteria growth.

When to See a Doctor

If body odor persists despite these measures or is accompanied by excessive sweating, rashes, or other unusual symptoms, consult a healthcare provider. Persistent odor could signal an underlying condition that needs attention.
