What causes light pain on the lower abdomen after eating food?
Patient: Hello, Dr. Siegel, I am a female of 60. For about 4-5 months I have been experiencing the coming and going dull pain, or in better words fullness and discomfort, at the left side above the waist line. Exactly at the side, and covering a small area in front and a little at the back. mostly after a meal. Would you please response at  YYYY@YYYY ?Thank you very much. Doctor: HelloAs you mentioned that this pain is from last 4-5  months , typically after meal ( mostly ) , this type of pain may be due to these reasons , these includes.1 Hyper acidity or gastritis or Hiatus hernia or Peptic ulcer disease , as all these are nearly  same , so need not to worry about name . Diagnosis can be confirmed by upper G I endoscopy. Try raising the head of your bed about 4 inches with blocks. It might also help to avoid eating or drinking for 2 hours before you lie down. To help control stomach acid one should not drink alcohol or drinks with caffeine in them or eat chocolates or spicy or greasy foods. Also take some antacid but if pain is severe you may need drugs like proton pump inhibitors ;like pantaloc-D once or twice in day.2 As you mentioned that pain is near waist line and also radiating in the back , so this may be due to renal calculus . Diagnosis can be confirmed by ultrasound of both kidneys .3 Amoebic colitis is the another most common cause of this type of pain . Diagnosis can be confirmed by physical examination by a physician . Stool examination also find entamoeba histolica .In ,my opinion consult a physician and get his opinion as above mentioned above.Good luck.
