Hi, Itching during pregnancy is a common issue and can have various causes. In some cases, hormonal changes during pregnancy can cause dry skin, leading to itching. Additionally, increased blood flow during pregnancy can also cause itchiness in various parts of the body. However, severe itching during pregnancy can also be a sign of a more serious condition called obstetric cholestasis, which affects the liver and can be harmful to the baby. Given that you have itching on your scalp and body along with sores and hair loss, it is advisable to see a healthcare provider for evaluation. They can determine the underlying cause of your itching and provide appropriate treatment. In the meantime, avoid scratching the affected areas to prevent further damage, and consider using mild, fragrance-free moisturizers or creams to soothe the skin. If you require a personalized response, kindly use the Ask A Doctor service and post a follow-up. Take care. Hope I have answered your question. Regards, Dr. Priyanka, General & Family Physician
