Anxiety and stress are never good for health. However, both are extremely common during pregnancy. While most people feel that stress is a normal part of pregnancy, it is not always true. Women do tend to develop anxiety while they are pregnant but this is not true for all pregnant women.
Stress becomes a symptom of pregnancy because there are several physical and chemical changes in the body during pregnancy. These changes, along with the several hormones, fluctuating sugar levels, pregnancy related anemia, change in the blood circulation, indigestion and the change in your overall physical appearance, can together overwhelm you and put you under a lot of stress.
No need to panic yet though. Stress and anxiety are normal during pregnancy and with a little support from your partner, friends and family, stress during pregnancy is nothing that you cant handle.
