Causes of itchy and irritated armpits

Itchy armpits are a prevalent symptom that can have different causes, some easy to treat and others that will require medical attention. It is essential to be attentive to this symptom since, in addition to being very annoying, it can be the beginning of an infection, which, if not treated quickly, can worsen and even require antibiotics.

The armpits are an area of ​​the body exposed to certain irritants. Still, it is also an area that accumulates sweat, that is, humidity and heat, making them an ideal space for pathogens to develop. This is why itchy armpits can be due to different reasons. Among them are the following:

  • Inadequate hygiene: bacteria can develop in this area that, in addition to a bad smell in the armpits, can cause itching.
  • Personal hygiene products: soaps, perfumes, moisturizers, deodorants, or antiperspirants can cause allergies. The main factor generating allergies in the armpits is deodorant, so it is essential to rule out if this is your case by observing when the irritation appears or when it worsens.
  • Clothing: Fabrics or other synthetic materials that contact the skin can irritate the armpits. If you associate the itching with specific garments, stop wearing them and try using other cotton ones. This material does not cause allergies but is currently rarely used.
  • Irritated armpits from waxing: removing underarm hair can irritate the skin, either when shaving or waxing. In addition, this can cause the hairs to grow back to ingrown, which causes itching and pain and can even become infected and become a pimple with pus.
  • Itch in armpits due to fungi: the armpit area can hold a lot of humidity as it is a part of the body that concentrates sweat glands. This humid and warm environment can favor the appearance of fungi, as it happens in other parts of the body. This will undoubtedly cause irritation and itching.
  • Serious Illnesses – Itchy armpits can be a symptom of more severe illnesses such as chronic kidney failure, chickenpox, psoriasis, scabies, blocked bile ducts, and Hodgkin’s disease.
  • Other causes: dry skin, certain drugs, mammary glands that become activated during pregnancy, extreme cold or heat, and stress can also lead to itchy armpits.

Itching in the armpits can be treated at home. If the condition is not severe, it is better to go to the doctor.
