Foods to avoid while taking Metformin

For the millions of Americans with diabetes, one medication often can help manage their disease — Metformin (Glucophage). Metformin lowers blood glucose levels, which helps minimize the need for insulin or other medications. In addition, while taking Metformin, you’ll be less likely to develop conditions like heart disease and high blood pressure. But while taking this medication, it’s essential to know what foods to avoid to prevent unwanted side effects. These are some of the most common foods to avoid while taking Metformin. In this article, we will discuss foods to avoid while taking Metformin.


What is Metformin?

Metformin is a medication that helps lower blood sugar levels and can help people with type 2 diabetes. It is also prescribed for other conditions, such as PCOS, obesity, and gestational diabetes. Metformin is often used with lifestyle modifications and may be combined with other oral medications or insulin injections. To get the full benefit of this medicine, you need to take it exactly as your doctor prescribes. It would help if you did not stop taking this medication without first talking to your healthcare provider. The most common side effects are stomach upset and diarrhea; however, you should talk to your doctor about any side effects that bother you or do not go away.


6 Foods to Avoid While Taking Metformin

Metformin is a type of drug that has been used for decades in the treatment of diabetes. It helps the body use insulin more effectively and lower blood sugar levels. Metformin should be taken regularly because it can take up to six weeks before you start feeling its effects. Metformin may cause side effects if not taken as prescribed, including stomach pain, nausea, vomiting, loss of appetite, diarrhea, and confusion. Eating certain foods may also increase some of these side effects.

Below are five foods that you should avoid when taking Metformin:


Simple and refined carbohydrates

High fiber foods






Eating certain fats can make it more difficult for your body to process and remove the medication from your bloodstream, leading to side effects such as nausea, vomiting, and diarrhea. Avoid saturated fats like butter, lard, and bacon grease. Instead, opt for oils high in monounsaturated fat, like olive oil, canola oil, or peanut oil.


Simple and refined carbohydrates

Metformin is a medication that helps the body lower blood sugar levels. This drug is often prescribed for people with type 2 diabetes and insulin resistance, but it can also be prescribed for other conditions. Metformin works by decreasing the amount of sugar your liver produces and the amount of sugar absorbed from food. It also increases sensitivity to insulin so that more glucose is transferred from the blood into muscles instead of fat cells.


High fiber foods

High-fiber foods such as grains, vegetables, and beans can help lower blood sugar levels. However, foods that are increased in fiber are also inferior in the glycemic index. The glycemic index measures how quickly your body breaks down food into sugar. Generally, the higher the number on the glycemic index, the quicker your body will break down that food into sugar.



It is essential to keep an eye on your sodium intake, as high levels can be dangerous for patients with diabetes. In addition, avoiding foods high in sodium is an excellent way to keep your blood pressure and heart health. 

The American Heart Association recommends limiting the amount of salt you consume to less than 2,300 milligrams per day. That’s equal to one teaspoon of salt per day.



Excessive alcohol consumption should be avoided because it can lead to hypoglycemia and other serious side effects. Alcohol also interferes with the absorption of some medications, such as Metformin.



Metformin is typically prescribed for type 2 diabetes and can be used to treat polycystic ovary syndrome (PCOS). Furthermore, metformin is also used with other medications as a first-line treatment for gestational diabetes.

Metformin can cause stomach upset, nausea, diarrhea, and vomiting. In some cases, it may also cause low blood sugar. Patients should speak with their doctor about what foods to avoid.


Foods to Include in a Metformin Diet

Many people with diabetes take Metformin to help control blood sugar levels. Metformin is a big word for drugs used to treat type 2 diabetes, prediabetes, and polycystic ovary syndrome (PCOS). Metformin helps reduce insulin resistance in the body, which can help make your body more sensitive to its insulin. However, like any medication, there are some foods that you should not eat if you’re on Metformin. These include: 

– Alcoholic beverages 

– Caffeinated drinks like coffee and tea 

– Citrus fruits or juices 

– Sugar substitutes, including Stevia 

– Carbonated beverages such as soda and sparkling water


When Should You Take Metformin?

Metformin should be taken as prescribed by your doctor, typically at the same time each day. Taking it simultaneously each day is essential to help keep blood sugar levels steady and prevent or control diabetes. Metformin can be taken with or without food, although eating a meal before taking your medicine is recommended. If you’re on a low-carbohydrate diet, it’s best not to take Metformin with orange juice or other fruit juices high in natural sugars because this may increase blood sugar levels.


Other Things to Avoid While on Metformin

Metformin is a drug that helps control blood sugar levels. It works by reducing the amount of glucose produced by the liver and decreasing the absorption of sugar from food in the intestines. However, Metformin can cause side effects such as diarrhea, nausea, vomiting, stomach pain, loss of appetite, weight loss, and increased feelings of thirst. It can also lead to low levels of vitamin B12 and folic acid, which may cause problems with brain function or nerve damage.


Look at the Overall Diet

Metformin is a medication that helps manage blood sugar levels in people with diabetes. It does this by slowing down the release of sugar from the liver into the bloodstream. Metformin does not generally cause problems unless taken with certain foods or other medications, affecting how well it works. The following is a list of foods that should be avoided when taking Metformin: 

1) Alcohol (including beer, wine, and hard liquor) 

2) Fruits containing high amounts of fructose 

3) High-fat foods 

4) Large quantities of carbohydrates (bread, pasta, rice, and potatoes) 

5) Raw vegetables and raw fruit juices because they contain large amounts of natural sugars
