Can malabsorption be the reason for random rashes, a couple swollen lymphnodes, i don't digest food (don't know why) since i delivered a premature birth?

INDIGESTION: Gi problem may not be related to the rashes or swollen lymph nodes or premature delivery. Have yourself checked.

Yes it can: Malabsorption or GI dysfunction can cause all the symptoms that you described because your GI (gut) health is very important for your immunity.....If you don't have a very effective GI system then other systems (skin, lymph) need to be more active and can be overwhelmed.... To help your GI system, please use a very high end probiotic of at least 25 billion cfu and consider colostrum therapy.
