Weight loss injections, HRT and Bleeding..

The use of GLP-1 (glucagon-like peptide-1) receptor agonists ( or "weight loss injections" as many people know them as ) is becoming a popular treatment for weight loss and type 2 diabetes and for some groups - like those who've gained weight during the menopause,  they've gained a lot of popularity due to their effectiveness in weight management. 

HRT is often prescribed to alleviate symptoms of the menopause, such as hot flushes, aches and pains and mood swings so when combining GLP-1's with HRT, it's important to be aware of potential side effects, particularly bleeding issues.

While GLP-1s are primarily recognised for their metabolic benefits, they might sometimes lead to changes in your bleeding patterns, including breakthrough bleeding and even when you haven't had a bleed for years. This can be concerning if you're on HRT, which also influences the menstrual cycle by stabilising hormone levels. To mitigate bleeding complications, it's important to be aware of the clinical advice relating to this particular combination of treatments.

Firstly, it's really important to let your GP or other healthcare professional know that you're using weight loss medication alongside your HRT.
GLP-1's can cause you to start bleeding but so can weight loss which has occurred in a short period of time - your GP will help establish the likely cause of your bleeding and help you manage this safely.

If you're just starting out with GLP-1 therapy alongside your HRT, the  British Menopause Society has issued  clear advice to address the need for oral forms of progesterone/progestogen to be increased when you first start using weight loss injections for  the first 4 weeks, and then for 4 weeks again each time your injection dose is increased.

Secondly,  if you start bleeding - let your GP know. You might think it will settle and feel that it's associated with starting the injections, but it's important not to  assume that the two are related. Your GP may wish to offer you an examination and refer you for a transvaginal scan to make sure that your womb lining is not over-thickened. 

Lastly, if your bleeding persists or is worsening despite  getting the all-clear from your GP, it might be necessary to explore alternative HRT options such as switching to non-oral progesterone and considering a combined patch for example or even changing to a hormonal coil.

With proper monitoring and communication with your healthcare provider, it's possible to navigate the combination of weight loss injections and HRT safely and effectively and optimise the benefits of both of these therapies while minimising potential risks.
Please let your GP know of any new bleeding you experience while using HRT.
