Pregnancy related skin rashes
Pregnant women are very susceptible to a wide range of skin rashes, which are usually due to the massive hormonal changes occurring in your body. However, always check with your doctor or midwife if you experience persistent problems.
It is not unusual to develop dry patches of flaky and highly itchy skin,most commonly on your legs, arms, and abdomen. Applying simple moisturizing creams usually helps, but occasionally an antihistamine or even low-dose steroid cream may be needed to relieve irritation. The dilated blood vessels in your skin may make it look pinker, or even blotchy, which can sometimes be mistaken for a rash.
Since your skin needs to get rid of the extra heat from these dilated blood vessels, it is normal for you to sweat more. As a result, you may develop a sweat rash under your arms or breasts and in the groin areas, where sweat accumulates and does not have much chance to evaporate quickly.
Wearing looser clothes, preferably cotton, and avoiding synthetic fabrics close to your skin will reduce the problem, as will careful hygiene and using unscented soaps and deodorants.
Occasionally, a swear rash can become infected with a fungal organism, for example, yeast. These are not serious, but can make you itchy and uncomfortable and you may need a prescription topical antifungal cream to help clear the infection.
