I am in my fourth month of pregnancy and I am going through a severe bout of hot flashes. Is it normal? Can anybody suggest some home remedy?

Yes, it's perfectly normal to experience hot flashes during pregnancy. I's because of the change in the hormone levels during pregnancy which increases the blood flow to the skin. Have healthy diet and increase your protein intake. Protein helps with hormone production in the body. High protein foods include meat, fish, cheese, tofu, beans, lentils, yogurt, eggs, nuts, and seeds.
