Foods to Avoid while taking Metformin

If you are a diabetes patient and taking metformin for treatment and confused about what you should eat and what you should not, there are some points that you should take care of and know about metformin. There are some food items that you should avoid while taking metformin, for example, high-fat and carbohydrate food, alcohol, caffeine, grapefruit, etc to get better results from metformin. Let’s explore the foods to avoid while taking Metformin in this article.

What is Metformin?

Metformin is a medicine that is given in the treatment of type 2 diabetes. It works by decreasing the amount of glucose (sugar) that is produced by the liver and absorbed by the intestines, and increasing the body’s sensitivity to insulin, a hormone that helps the body use glucose for energy. Long-term complications of diabetes, such as nerve damage, kidney disease, and eye problems can be prevented by controlling your blood sugar level.

Metformin is typically taken orally, usually two or three times a day, with meals. You can take metformin alone or with a combination of other drugs as instructed by your doctor. It is important to take metformin as instructed by your doctor. Regularly monitor blood sugar levels regularly to ensure that the medication is working effectively.

In addition to its use in diabetes management, metformin is sometimes used to treat other conditions, such as polycystic ovary syndrome (PCOS) and obesity. It is generally considered safe and effective, but like any medication, it can cause side effects, such as gastrointestinal symptoms (nausea, diarrhea, abdominal discomfort), vitamin B12 deficiency, and in rare cases, lactic acidosis, a serious condition that can occur when there is a buildup of lactic acid in the body.[2]

Foods to avoid while taking Metformin

It is important to be mindful of certain foods that can interact with metformin and affect its effectiveness, absorption, and side effects. Here are some foods that should be avoided while taking metformin:

Alcohol: The risk of lactic acidosis increases due to the consumption of alcohol while taking metformin. Lactic acidosis is a rare but very serious side effect of metformin.

High-carbohydrate foods: Foods that are high in carbohydrates can raise blood sugar levels, which can counteract the effects of metformin. Therefore, it is best to avoid high-sugar content drinks.
High-fat foods: Foods that are high in fat can slow down the absorption of metformin, reducing its effectiveness. Avoid fatty meats, fried foods, and high-fat dairy products.
Grapefruit: Grapefruit can interact with some medications, including metformin, and interfere with how the body metabolizes the medication.

Caffeine: Caffeine can increase the risk of side effects such as nervousness, jitteriness, and heart palpitations. You should limit caffeine intake.

It is important to talk to your doctor and ask them what you should eat or not to prevent any side effects

Food to take while taking Metformin

When taking metformin, it is important to follow a healthy and balanced diet that supports your overall health and helps manage blood sugar levels. Here are some foods that you can include in your healthy diet:

High-fiber foods: Foods that are high in fiber can help regulate blood sugar levels and improve insulin sensitivity. Fruits, nuts, legumes, vegetables, and whole grains are examples of high-fiber food.
Lean protein: Protein can help slow down the absorption of carbohydrates and improve satiety. Turkey, fish, and tofu are good sources of lean protein.
Healthy fats: Healthy fats can help in reducing inflammation. Examples are nuts, seeds, avocados, etc.

Low-carbohydrate vegetables: Vegetables that are low in carbohydrates and high in fiber are ideal for diabetes patients. Examples are broccoli, spinach, cauliflower, zucchini, etc.
Berries: Berries are rich in antioxidants and fiber and have a lower glycemic index than many other fruits. Examples of berries are blueberries, strawberries, etc.
Water: While taking metformin it is important to stay hydrated. To prevent dehydration drink water and keep your body hydrated.

It is important to take advice from your doctor or dietician before you start these and tell them all the history. Avoid if you have an allergy to any of the above-mentioned food items

When should you take Metformin?

The dosing and timing of metformin can vary depending on the needs of the individual. Always follow instructions provided by your doctor and written on medication.

In general, metformin is usually taken orally, with meals, and typically 2-3 times a day. This can help reduce gastrointestinal side effects, such as nausea or diarrhea, that can occur when taking metformin on an empty stomach.

It is important to take metformin at the same time each day to maintain consistent blood levels of the medication. Take your dose as soon as possible if you forgot to take your dose. Skip that dose if it is late and continue with another dose.

Monitor your blood sugar level continuously to ensure the effectiveness of metformin in case you are taking it for the first time or changing doses.

Adverse effects of Metformin?

Metformin is generally considered safe and well-tolerated, but like any medication, it can have potential adverse effects. Here are some of the common adverse effects:

Gastrointestinal side effects: Digestive system side effects are the most common side effects of metformin. These include diarrhea, nausea, abdominal discomfort, and flatulence. These side effects can occur in up to 50% of people taking the medication.
Lactic acidosis: This is a rare but potentially serious side effect of metformin. It occurs when there is a buildup of lactic acid in the bloodstream. Lactic acidosis can cause symptoms such as weakness, fatigue, shortness of breath, abdominal pain, and confusion. People with kidney or liver disease and chronic alcohol drinkers are more likely to develop it.[1]
Hypoglycemia: Metformin can lower blood sugar levels, and in rare cases, it can cause hypoglycemia (low blood sugar). This is more likely to occur in people who have other conditions that can affect their blood sugar levels, such as kidney or liver disease, or those who are taking other medications that lower blood sugar.

Vitamin B12 deficiency: Metformin can cause vitamin B12 deficiency by decreasing its absorption. Fatigue, weakness, and tingling in the hands and feet all are symptoms of vitamin B12 deficiency.
Other side effects: Other potential adverse effects of metformin include a metallic taste in the mouth, reduced appetite, and skin reactions such as rash and itching.

Most people using metformin do not get any side effects. But if you are feeling something wrong immediately meet your doctor and tell them.
