Please explain

Patient: To tell the truth, i am not sure if this has to do with menopause or not and that is why i am writing… i am almost 47 yrs old and am REALLY going through hot flashes (seems like every 5 mins… dont know if that is normal)… that is not my problem… lately, my stomach looks like i am abt 8 mos pregnant. i am tired all the time and i have gas and it almost feels like i have to have a bowel movement. the next day i wake up and my stomach is smaller. when it is big, i feel something moving. i dont have insurance. is this just gas?
