Hi! Many find that during peri they become intolerant of in particular, alcohol

as well as other foodstuffs that were well tolerated.
Hormones can certainly affect the digestive system, top to bottom. Certainly within 10 mins of a bleed I would have to dash to the loo with 'the runs', even if a period wasn't due

. I would sometimes be extremely thirsty in the days leading to a bleed, as well as nauseous.
In recent years I've had to alter my diet drastically - I found that processed foods upset my bowel actions so gradually we have cut out a lot of shop bought cake, biscuits, processed anything at all. Slow transit is still problematic especially if we are travelling.

. U may find that taking a note of what you eat/drink for 3-4 days and when, will give you an idea if hormones have caused any sensitivity - rarely allergic reactions as these would be more drastic and U would certainly know.
Often I have problems from mid-afternoon, we haven't yet worked out why I feel very windy and bloated to the extent that I am unable to eat 'tea'. Having to wait until later in the evening, often 4-5 hours B4 I am able to face food.
We have threads about most things: books, hobbies, exercise ....... and menopause. Let us know how U get on, browse round; make notes ;-). Ask away.
