Why am I not losing weight with hypothyroidism?

Losing weight with hypothyroidism can be perceived as more difficult, even with healthy lifestyle habits.

Lipedema or obesity – how can you tell the difference?

Understanding why the body does not always respond as expected to diet and physical activity is an important starting point for the right treatment.

CagriSema – combination treatment under development for weight loss

CagriSema is a drug treatment under development for obesity. It combines two active substances, semaglutide and cagrilintide.
