I have a friend who has limited access to health care and is afraid of going to see a doctor knowing it will cost her 'an arm and a leg'. Besides, her fear of not getting a satisfactory answer adds to the problem and prevents her from seeing a doctor. Here is the issue: each and ever time she consumes acidic foods or beverages, even in small amounts, she has menstrual-like bleeding, with the usual bloating, fatigue, irritability, minor back pains, clotting, and stomach pain similar to her actual menstrual flow. She usually goes on to have her normal period almost 28 days (+/- 1 day) after her last. Our initial fear was ovarian cancer, but ovarian cancer does not explain why it only happens when she consumes acidic beverages. The only logical link (logical from a non-medical POV) between her digestive system and her reproductive system in this case seems to be an allergic reaction caused by sodium benzoate and other acidic products prevalent in processed foods entering the blood stream and affecting her ovaries. Is this reasoning logical and in accordance with a medical diagnosis? What is the actual problem and what can be done besides abstaining from acidic food which is an almost-impossible feat? Can you help with any information regarding this problem? Thanks in advance.
