It is very difficult. .. and still is with knowing some of the causes.

To help: keep a journal .. what foods you ate .. your symptoms or non-symptoms from them. Do the same with any medications you take. Take note of how your body reacts to stress .. physical and mental.

Try eliminating some usual culprits of foods …. like dairy, gluten, sweets, greasy foods .. and do it one at a time. That way you know what you can eat and not eat. With me .. sometimes I may have a problem with a food and the next time not. Our bodies are just weird at times.

Read the literature that came with any prescription drug you take or look it up online if you no longer have those papers. … look up the side effects of non-prescription drugs you take too. Ask your doctor or ask your pharmacist about a different drug you can take if a drug seems to be the problem. Pharmacist can be a good friend in figuring out drugs … you could even be taking them the wrong way with your other medications.

Our digestive systems can change as we age. What we used to be able to eat we may not tolerate because of a disease or we all of a sudden become sensitive or even allergic to something we have eaten or a drug.

Best of luck in dealing with your issues.
