3.Celiac Disease
If you have this, your body reacts to gluten, a protein found in wheat and other grains. When you eat it, your immune system — which helps you fight off bacteria and other germs — attacks your small intestine by mistake. That can make it hard for your body to take in nutrients, and that can lead to weight loss. You also may have headaches, itchy skin, sores in your mouth, and joint pain. Only a doctor can tell you for sure if you have it. If you do, you’ll need to follow a special diet to stop the symptoms.
4.Stress
It’s normal to drop a few pounds after something like losing a job, a divorce, or the death of a loved one. You should return to your regular weight once you have time to grieve the loss or get used to the change. You may need help from family and friends, group therapy, or a professional counselor. Talk to your doctor if you keep losing weight.
