@Sarah69 I'm still not sure what's going on with you, but I think it's clear that the metformin needs to be replaced with a medication that does not cause loss of appetite and nausea. Glad you've set up an appointment with the GP.
I'm so glad Indy51 thought to ask you if you're taking a multi-vitamin. Metformin depletes vitamin B12. This is important. You need to ask your doctor to check your B12 level. If your B12 level is chronically low over a period of time, it can make you very, very ill. Note the bolded symptoms near the end of the list.
Symptoms of a vitamin B12 deficiency can include: (
6)
- Constantly feeling tired or chronic fatigue
- Muscle aches and weakness
- Joint pain
- Difficulty breathing or shortness of breath
- Feeling dizzy
- Poor memory
- Inability to concentrate well
- Mood changes, like increased depression and anxiety
- Having abnormal heart problems, such as palpitations
- Poor dental health, including bleeding gums and mouth sores
- Digestive problems like nausea, diarrhea or cramping
- A poor appetite
- A more serious deficiency can also cause a form of anemia called pernicious anemia, a serious condition that can cause memory loss, confusion and even long-term dementia
