Does Taking Ezetimibe Cause Weight Loss in Heart Patients? - Internal Medicine

Will taking (Eito tablets) lead to weight loss?


Hello doctor, my father is 81 years old and is a heart failure patient.
He has a stent implanted in his heart.
The doctor hopes to lower his cholesterol, so he prescribed 40 mg of Lipitor (atorvastatin) once daily.
This summer, an additional 10 mg of Ezetimibe was prescribed, also once daily.
Yesterday, his cholesterol was measured, and his low-density lipoprotein (LDL) cholesterol was 26.
However, he has recently been experiencing a trend of weight loss, having lost 3 kg.
Can taking Ezetimibe cause weight loss?

Hello, thank you for your question.
This issue is more related to cardiology, so I recommend consulting a cardiologist.
The Allergy, Immunology, and Rheumatology Department of Changhua Hospital, Ministry of Health and Welfare, is concerned about you.

Ezetimibe, commonly known by its brand name Zetia, is a medication primarily used to lower cholesterol levels in the blood. It works by inhibiting the absorption of cholesterol from the intestine, which can lead to a decrease in low-density lipoprotein (LDL) cholesterol, often referred to as "bad" cholesterol. In your father's case, he is taking both atorvastatin (Lipitor) and ezetimibe to manage his cholesterol levels, which is a common combination for patients with high cholesterol, especially those with a history of heart disease or heart failure.

Regarding your question about whether taking ezetimibe can cause weight loss, it is important to note that weight loss is not a commonly reported side effect of ezetimibe. The primary goal of ezetimibe is to lower cholesterol levels, and while some patients may experience changes in appetite or gastrointestinal side effects, significant weight loss is not typically associated with its use.
However, there are several factors that could contribute to your father's recent weight loss:
1. Dietary Changes: If your father has made any changes to his diet in response to his cholesterol management, such as reducing saturated fats or increasing fiber intake, this could lead to weight loss.

2. Medication Side Effects: While ezetimibe itself is not known to cause weight loss, some patients may experience gastrointestinal side effects such as diarrhea or nausea, which could indirectly lead to reduced caloric intake and weight loss.

3. Underlying Health Issues: Given that your father has heart failure and has had a stent placed, it is crucial to consider that weight loss could also be a sign of worsening health or other underlying conditions. Heart failure can sometimes lead to unintentional weight loss due to fluid shifts, decreased appetite, or increased metabolic demands.

4. Physical Activity: If your father has increased his physical activity levels, even slightly, this could also contribute to weight loss.

5. Fluid Retention: In heart failure patients, weight can fluctuate due to fluid retention. If he has been losing excess fluid, this could also reflect as weight loss.

It is essential to monitor his weight and overall health closely. If the weight loss is significant or accompanied by other concerning symptoms (such as fatigue, weakness, or changes in appetite), it would be advisable to consult with his healthcare provider. They may want to evaluate his overall health status, review his medications, and possibly adjust his treatment plan if necessary.

In summary, while ezetimibe is not typically associated with weight loss, various factors related to diet, medication side effects, and underlying health conditions could contribute to your father's recent weight changes. Regular follow-up with his healthcare provider is crucial to ensure that his heart condition and cholesterol levels are managed effectively.
