Causes of Itching all Over the Body

Itching, also called pruritus, commonly occurs due to skin disorders, and may affect sleep or quality of life if the condition is severe. Rooted in the nerve endings, itching all over the body is called generalized pruritus. This condition may serve as a clue to the presence of an underlying systemic disease, according to the American Academy of Family Physicians.


Hyperparathyroidism occurs when an excess of parathyroid hormone in the blood impacts the levels of calcium in the body. Primary hyperparathyroidism causes high levels of calcium, whereas secondary hyperparathyroidism causes low levels of calcium. MedlinePlus reveals that in both cases, the condition may cause itchy skin, as well as back pain, blurred vision, bone pain, depression, fatigue, bone fractures, loss of appetite, nausea and pain in the upper abdomen. If calcium levels don't impact health, treatment may be unnecessary; however, in some cases surgery to remove the parathyroid gland may be indicated.


Cholestasis refers to any condition in which blockage of bile from the liver occurs. MedlinePlus indicates causes both inside and outside the liver, including bile duct or pancreatic tumors, cysts, pancreatitis, bile duct stones, alcoholic liver disease, lymphoma, pregnancy, tuberculosis or viral hepatits. Skin itching happens as a result of cholestasis, as well as unusually colored stools or urine, nausea and vomiting, yellow skin or eyes, inability to digest some foods and upper abdomen pain. Treatment of underlying conditions is necessary to manage cholestasis.

Hodgkin's Disease

Hodgkin's disease, a type of cancer called lymphoma, may cause body itching, as well as night sweats, fever, tiredness, weakness, coughing and shortness of breath, swollen lymph nodes and weight loss. This cancer of the lymphatic system impacts the immune system's ability to filter out bacteria and viruses. Chemotherapy and radiation are generally successfully at treating Hodgkin's disease, according to KidsHealth. Bone marrow or stem cell transplants may also prove effective.
