I am considering weight loss injections, and I am curious about their effectiveness and potential side effects.

My weight has been steadily increasing lately, and since I feel that diet and exercise alone are reaching their limits, I am seriously considering weight loss injections. When I search online, I find there are various types of weight loss injections, such as GLP-1 derivatives and fat-dissolving injections. I am curious about the actual extent of their weight loss effects and how realistic it is to say that one should not rely solely on these injections. Many descriptions mention that commonly used injections are administered subcutaneously once a week, starting at 2.5mg and increasing the dosage every four weeks; I would also like to know what BMI or co-existing conditions are typically used as the basis for prescribing these injections. Additionally, I am concerned because I have heard that gastrointestinal side effects such as nausea, vomiting, and diarrhea are common in the initial stages. I would like to know how frequently these side effects occur when starting the injections and how long it usually takes for the body to adapt. Finally, could I consult with you regarding whether I need to make regular outpatient visits while receiving injections while working, the likelihood of a rebound effect after stopping the injections, and whether considering weight loss injections is appropriate given my current weight and health condition?
