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

When a person stops taking GLP-1 medicines, their heart health does not immediately deteriorate, but the protective effects that the medication provided may gradually disappear, according to Dr Parin Sangoi, a Consultant Interventional Cardiologist. The immediate benefits of GLP-1 medicines on blood sugar, appetite, body weight, and various cardiovascular risk factors fade over time once the medication is discontinued.

Dr Sangoi emphasized that the concern is not about experiencing a heart attack due to abruptly stopping the medicine, but rather the potential return of the risk factors that the medicine had been managing. Weight regain, increased blood sugar levels, higher blood pressure, and worsening metabolic health can contribute to an increased cardiovascular risk over time.

Studies have shown that drugs like semaglutide can significantly reduce major cardiovascular events while patients are on treatment. However, these cardiovascular benefits are not expected to persist after the medication is stopped. Moreover, evidence suggests that discontinuing weight-management medications can result in considerable weight regain and the reversal of some cardiometabolic improvements.

The extent to which cardiovascular protection continues after stopping GLP-1 medicines varies from person to person, and there is a lack of long-term data examining protection following discontinuation.

It is crucial to consult with the prescribing doctor before stopping GLP-1 medicines, as abrupt discontinuation is not recommended. For individuals with diabetes, blood sugar levels may rise again after stopping the medication, while those taking GLP-1 drugs for obesity might experience weight regain. For people with existing cardiovascular disease, it is essential to consider the reasons why the medication was prescribed and whether alternative treatments are necessary to manage their risk factors.

If stopping GLP-1 medicines is due to side effects, cost, plans for pregnancy, or other medical reasons, the prescribing doctor can determine if the dose should be modified, another medication should be started, or more frequent monitoring is required. After stopping treatment, regular monitoring of weight, blood pressure, blood sugar, and other cardiovascular risk factors can help identify changes early and enable prompt intervention if needed.
