Losartan is a medicine used to treat high blood pressure. Many people take it to help keep their hearts healthy. But, some people wonder if it raises blood sugar levels. This is an important question for those with diabetes or those worried about it.
What is Losartan?
Losartan belongs to a group of medicines called angiotensin receptor blockers (ARBs). It helps relax blood vessels. This lowers blood pressure. It also helps prevent strokes and heart attacks. Doctors often prescribe losartan to people with high blood pressure.
Understanding Blood Sugar Levels
Blood sugar is the amount of sugar in your blood. Our bodies use sugar for energy. People with diabetes must watch their blood sugar levels closely. High blood sugar can lead to serious health problems.

Does Losartan Affect Blood Sugar?
Many studies have looked at how losartan affects blood sugar. Most of these studies say losartan does not raise blood sugar levels. In fact, some research says it might help with glucose metabolism.
Research Findings
Study | Finding |
---|---|
American Heart Association Study | Losartan is metabolically neutral. |
Mayo Clinic Report | No significant effect on blood sugar. |
NIH Research | Losartan does not increase blood sugar levels. |
From these studies, we see a clear trend. Losartan does not raise blood sugar levels. Instead, it is safe for most people, including those with diabetes.
Comparison with Other Medications
Other blood pressure medications can affect blood sugar. For example, thiazide diuretics and beta-blockers may raise blood sugar levels. However, losartan does not share this side effect. This makes it a better choice for many people with diabetes.
How Losartan Works
Losartan works by blocking a specific hormone. This hormone usually causes blood vessels to tighten. When losartan blocks this hormone, blood vessels relax. This helps lower blood pressure. As a result, it does not interfere with how the body handles sugar.
Possible Side Effects of Losartan
Like all medicines, losartan can have side effects. Some people may experience:
- Dizziness
- Fatigue
- Headaches
- Low blood pressure
- High potassium levels
Most side effects are mild. Serious side effects are rare. Always talk to your doctor if you have concerns.
Who Should Take Losartan?
Losartan is often prescribed for:
- People with high blood pressure
- People at risk for heart disease
- Patients with kidney disease
If you have diabetes, losartan may be a good choice. It helps manage blood pressure without raising blood sugar levels.
Diet and Lifestyle
Even when taking losartan, diet matters. Eating healthy can help control blood sugar. Focus on:
- Fruits and vegetables
- Whole grains
- Lean proteins
- Low-fat dairy products
Also, stay active. Regular exercise helps manage blood pressure and blood sugar. Talk to your doctor about a plan that works for you.
Consulting Your Doctor
Always consult your doctor before starting any medication. They will help you decide if losartan is right for you. They can also monitor your blood sugar levels. This is especially important if you have diabetes.
