I don't take it but can give you an explanation of how it's supposed to work and why it doesn't work or doesn't work well for some Type 2's.

Ozempic is one of the drugs in the class GLP-1.

GLP-1 is made by our bodies naturally. When you eat and start digesting the intestines release it (it's a hormone) that tells the Pancreas to start releasing insulin to metabolize the carbs (sugars).

Once the food is digested your body stops producing it and the Pancreas (kinda turns off the insulin).

This is a problem with Type 2 because we always have "extra sugar" floating around. So GLP-1 drugs put the artificial hormone into our system to try and get the Pancreas to keep releasing insulin to deal with the "extra sugar".

As long as you are not "severely insulin deficient", about 10% of Type 2 are, then you have some insulin to release and it lowers your blood sugar. If you are then there is no insulin (left) and it doesn't work or doesn't work as well.

The hormone itself also tells your brain "I'm full" which is how it helps "some" lose weight - it stops some from eating "extra food" or snacks between meals or allows you to feel satisfied with smaller meals.

If it doesn't work for you then there is only about one other class of drugs that "might help", otherwise, insulin would be the next/final treatment.
