I've had stomach cramping for sometime with constipation and diarrhea, unexplained weight loss of around 25 lbs last couple of years with hair loss and brittle nails, some Crohns. Really had stomach problems my whole life. Just found out today my EPI # is 137 marked as LOW. It's not severe but low. Also have a lesion on my pancreas. Haven't even talked to my G.I. doctor yet. Will I need treatment for this #. If so, hoping I can take OTC enzymes.
