I am in my second trimester and I keep scratching my body all day. What's happening? Is this normal?

It is normal for your skin around your tummy area to itch when you are pregnant, as your skin begins to stretch to accommodate the growing baby. Also, hormonal imbalance can dry out the skin, leading to itchiness. However, if you are feeling severe itching and all over the body, it could be a case of intrahepatic cholestasis, a type of liver condition. Please visit the doctor immediately as in severe cases the condition can also lead to stillbirth.
