Hi Menopausalalways - have you tried any other hrt products? The progestin in evorel can bring really harsh side effects for some women. If you prefer combined patches you could ask to try Femseven. The mirena coil has the same progestin as Femseven and is useful if you’re still having problematic bleeding with other forms of hrt.
In terms of bowels, progesterone/progestins can cause problems as they slow the movement of the digestive tract and when they are stopped/lowered, the bowls kick in again. Low oestrogen in untreated menopause is the culprit for a lot of digestive issues, including constipation and IBS.
It might be worthwhile asking for a different product before you rule out hrt entirely, if you get it right, you can feel really well.
Hope this helps.
