It could be that this HRT doesn't suit you bowel-wise but it may still settle down. Patches or gel are kinder on the stomach as they are not metabolised by the liver so this may be worth bearing in mind.
Anyone developing IBS symptoms for the first time over the age of 50 needs to mention it to the GP apparently. I use Buscopan prescribed by the doc and find it quite helpful on those mornings when it's proving difficult to get to work on time due to the need to get to the loo quickly and often!
