Type 2 diabetes and weight loss injections: what to know

Many of these medicines act on gut hormones, including GLP-1. They can slow stomach emptying, reduce appetite and help the body release insulin when glucose is high. Some people also notice nausea, constipation, diarrhoea or vomiting, particularly after starting or increasing a dose. These medicines are not suitable for everyone, and they do not replace a personalised diabetes plan.

Your clinician may review kidney function, other medicines, digestive symptoms and any history that affects safety. A weight change can be one treatment goal, but glucose readings, blood pressure, daily function and your overall health also matter. Learn more about <a href="/materials/glp-1-receptor-agonist/">GLP-1 Receptor Agonist</a> therapy and <a href="/conditions/type-2-diabetes/">Type 2 Diabetes</a>.

Take the medicine exactly as prescribed and do not change the dose because of a single reading or a missed injection. Keep a record of glucose readings, appetite, bowel symptoms and any vomiting. Eating smaller meals, drinking fluids and following an agreed activity plan may make treatment easier. Do not combine products or buy injections from an unverified source.

If weight gain is unexplained, mention it rather than assuming another injection is needed; the cause may require a different assessment. A structured <a href="/treatments/lifestyle-and-wellness/weight-management-programme/">Weight Management Programme</a> can complement medicine. Your clinician can also explain the separate role of <a href="/treatments/medical-management/weight-loss-injections/">Weight Loss Injections</a>.

Contact your diabetes team promptly for repeated vomiting, inability to keep fluids down, severe or persistent abdominal pain, faintness, or signs of dehydration such as very little urine. Seek urgent help for confusion, difficulty breathing, collapse or severe weakness. Ask for advice if glucose readings are repeatedly outside your agreed range, especially during illness.

Ask which medicine fits your diabetes treatment, what improvement to look for, how to manage a missed dose, and whether another medicine needs adjustment. Also ask how pregnancy plans, surgery, kidney problems or troublesome digestive symptoms could change the plan.
