Is celiac disease always associated with malnutrition?

Not always. Malnutrition can happen if someone's celiac dis is severe and long enough. Especially with fat soluble vitamins. The treatment of celiac dis is avoiding gluten. If the patient can do that strictly, the small intestine's absorption area returns to normal looking and normal function. The malnutrition will eventually go away.
No. Celiac disease is an autoimmune reaction to certain proteins in wheat, other grains. Can cause gas, bloat, cramps, pain, diarrhea. Can also cause weight loss (or gain if "eating around the problem"), iron deficiency with or w/o anemia, osteoporosis, other. Symptoms may be mild or not. See md, rd, get examined, appropriate lab tests.
