Causes: Inadequate digestion: Partial or complete gastrectomy, obstructive jaundice, biliary cirrhosis, chronic pancreatitis, fibrocystic disease of pancreas pancreatic carcinoma, lactase and sucrase deficiency, Zollinger-Ellison syndrome. Disease of intestine: a) Inadequate absorptive surface: Resection of the gut, regional enteritis, bypass surgery. b) Inflammatory or infiltrative disease: Amyloidosis, Scleroderma, lamphoma, various skin disorders, tuberculous enterocolitis, cosinophilic enteritis, ulcerative colitis, Crohn's disease. c) Biochemical abnormalities: Non-tropical sprue, Hartnup disease, Coeliac disease. d) Lymphatic obstruction: Tabes mesenterica, Lymphoma, Whipple's disease, Talengiectasia. e)Altered bacterial flora: Blind loop syndrome, gastrocolic fistula, di...

Relieve Rheumatoid Arthritis Foot, Ankle, and Toe Pain With These Moves

1 / 7 Foot Workout to Ease RA Pain Most people with rheumatoid arthritis (RA) at some point develop symptoms like pain, stiffness, and swelling in the foot and ankle. Exercise has been proven to help with these symptoms: one review of trials published in September 2016 in the British Medical Bulletin indicates that resistance exercises not only improve pain, they also increase hand function, grip strength, and range of motion in people with RA. But getting to the gym or through a workout can be tough. In addition to standard sweat session saboteurs like a lack of time or energy, people living with rheumatoid arthritis may also be anxious that working out may aggravate symptoms. In actuality, regular, gentle exercise does the exact opposite: It can help minimize swelling, promote flexibility, and maintain and improve range of motion. Not to mention that there are so many great moves you can do in the comfort of your own home; you ...
