What illnesses can lead to hair loss?
Any change in your body’s chemistry could potentially lead to hair loss. The loss usually begins around 2 to 3 months after a shock to the system from severe stress, high fever, surgery, child birth or menopause; or from a medical or nutritional problem like a vitamin or mineral deficiency, hypothyroidism, or chemotherapy. Even starting or stopping some medications can cause your hair to fall out. The hair loss caused by these problems is called diffuse hair loss or telogen effluvium. The good news is that, although you may lose hair from all over your scalp, you will not go completely bald. Your hair should begin to return to normal about three months after the problem is corrected.
