This is what happens to heart health when you stop GLP-1 medicines

GLP-1 medicines play a role in managing type 2 diabetes, obesity, and potentially reducing cardiovascular risk. However, when a person stops taking these medications, their heart health does not instantly return to its previous state, warns Dr Parin Sangoi, an Interventional Cardiologist at Wockhardt Hospitals, Mumbai Central. The beneficial effects on blood sugar, appetite, weight, and various cardiovascular risk factors gradually diminish as the drug is discontinued.

The immediate benefits of GLP-1 drugs, such as those like semaglutide, have been observed to decrease major cardiovascular events while patients are on treatment, according to Dr Sangoi. Yet, the extent of cardiovascular protection after stopping the medication varies from person to person, and long-term studies on this aspect are lacking.

Weight regain, increased blood sugar levels, higher blood pressure, and deteriorating metabolic health can lead to a greater cardiovascular risk over time. This is especially true for individuals taking GLP-1 medicines to treat diabetes or obesity, as well as those with existing cardiovascular disease.

Dr Sangoi emphasizes that abrupt cessation of these medicines does not cause a heart attack, but the previously controlled risk factors can resurface. Weight regain, rising blood sugar, blood pressure, and worsening metabolic health contribute to an increased risk of cardiovascular issues.

He advises against stopping GLP-1 medicines without consultation with the prescribing doctor, as the decision should be carefully planned. For those with diabetes, blood sugar levels may rise again upon discontinuation, while individuals using these drugs for obesity might experience weight regain. For those already dealing with cardiovascular disease, understanding why the medication was prescribed and considering alternative treatments to manage risk factors is crucial.

If a decision to stop treatment is based on side effects, cost, plans for pregnancy, or other medical reasons, the prescribing doctor can help determine if the dose needs modification, an alternative medication should be started, or more frequent monitoring is required. Regular monitoring of weight, blood pressure, blood sugar, and other cardiovascular risk factors after stopping treatment can aid in identifying changes early.
