See below. Constipation can present in several ways in general we would not expect constipation to present itself in an association with your menstruation. Several questions would help diagnose your problem. To include how often you normally move your bowels. Do you normally have a problem with constipation. Do you normally have pain in your pelvic and lower back area when you're constipated. Is your menstruation regular? Was this menstruation worse than your usual? Do you usually have cramping and discomfort at the time of your menstruation? A good rule of thumb in evaluating your bowel moment would include: bowel movement 1 to 3 times a day, the consistency of a banana, possibly floating, and six inches to a foot long. Other possibilities and more likely based on the small amount of data that I presently have is that you're having some type of hormone imbalance. Would suggest saliva testing to include estradiol, progesterone, testosterone, and DHEA. We would be happy to further discuss this issue in the concierge service at https://www.healthtap.com/dr-stevenfergusonmd.
Constipation. Constipation refers to bowel movements that are infrequent or hard to pass (+/- pain). Severe constipation includes obstipation (failure to pass stools or gas) and fecal impaction, which can progress to bowel obstruction and become life-threatening. Increasing dietary fiber, laxatives, enemas, medications (Colace, Amitiza (lubiprostone) and Linzess are effective) and sometimes even surgical intervention.
