What is Metformin?

The medication metformin is advised for the treatment of Type 2 diabetes, prediabetes, and insulin resistance. According to the CDC, 90 to 95 percent of the over 30 million diabetics have Type 2 diabetes. Metformin is a member of the biguanide drug family, which includes medicines that stop the liver from producing sugar. Metformin also enhances the body’s reaction to insulin and lowers the amount of sugar that is absorbed by the body from diet.

Foods to Stay Away From When Taking Metformin


The following six foods should be avoided when using metformin:


The best fats are the good fats. If someone is using Metformin, they make a fantastic, healthy diet. While using Metformin, stay away from foods high in trans and saturated fats.
Refined and simple carbohydrates:

Elevated blood glucose levels are caused by simple and processed carbohydrates. Avoid eating carbs like those found in pastries, soda, and candy. Avoid refined carbohydrates, such as white rice, white bread, and pasta.

Foods high in fibre

Fiber is considered to increase the absorption of several medications and decrease their bloodstream levels. Large fibre intake may cause a person’s levels of metformin to drop. Limit your daily fibre intake to 30 grammes or less.


When using Metformin, a person must avoid drinking too much salt. Limit your daily salt consumption to no more than 2300 mg.


Massive alcohol consumption should be avoided since it increases the risk of lactic acidosis and low blood glucose. Alcohol has been proven to inhibit the liver’s ability to store and release sugar. Because managing blood sugar levels is already difficult for diabetics, lowering the risk of alcohol use is something to think about. Alcohol consumption on an empty stomach may cause low blood sugar.

This is valid for those who use insulin or other diabetic medications that raise levels of insulin. It has been discovered that metformin increases lactate levels. The constituent that makes up lactic acid is lactate. According to research, a thiamine deficit and excessive alcohol use might result in lactate buildup. Combining alcohol with metformin may result in an abnormal buildup of lactic acid in the blood.

Lactic acidosis, a serious condition, might occur from this. Overall, moderate drinking is safe. One drink per day for women and two drinks per day for men are considered safe limits.


One investigation looked examined the impact of grapefruit on metformin. Researchers discovered that individuals who consumed both Metformin and grapefruit juice produced more lactic acid than those who just consumed Metformin. Additionally, they could put on additional weight.

Additionally, it was shown that grapefruit juice accelerated the accumulation of metformin in the liver. The generation of lactic acid then increased as a result. The trials also showed that people on Metformin may be more likely to develop lactic acidosis after eating

Grapefruit juice.

What impact does grapefruit have on metformin?

The same enzyme that breaks down the medications on the previous list does not break down metformin. It is excreted in the form of urine since the body does not digest it.

The interactions of grapefruit with metformin in non-diabetics were explored in a research. Only a few patients were exposed to both Metformin and grapefruit juice. Others received only Metformin exposure.

It was discovered that those who were exposed to both grapefruit juice and Metformin had increased levels of lactic acid production.

It was hypothesised that grapefruit juice accelerated Metformin accumulation in the liver. In turn, this led to an increase in the generation of lactic acid. It has been hypothesised that consuming grapefruit juice while taking Metformin may increase the risk of lactic acidosis.

Alcohol and Metformin

Alcohol generally requires diabetics to limit their alcohol intake since it inhibits the liver’s capacity to retain and release sugar. For diabetics, this is an issue since their bodies already struggle to control blood sugar levels. Additionally, consuming alcohol on an empty stomach runs the risk of causing low blood sugar (hypoglycemia).

The risk of this alcohol-related problem is higher in those who use insulin or diabetic medications that raise insulin levels. Since metformin does not increase insulin levels, those who take it are less likely to have alcohol-induced hypoglycemia.

Lactic Acidosis Related to Metformin

Lactic acid is produced when the body uses sugar as fuel. The bloodstream’s level of lactate, the fundamental component of lactic acid, is increased by metformin. This is often a benign consequence, however a study found that heavy alcohol consumption combined with thiamine (vitamin B1) deficiency may cause lactate to build up. In patients with acute or long-term alcohol misuse, the combination of metformin plus alcohol may result in an excess of lactic acid in the blood, a fatal condition that may lead to lactic acidosis.

Metformin-related lactic acidosis (MALA) is uncommon but potentially harmful. Although diabetics have a modest chance of developing lactic acidosis, this risk increases if the patient also has congestive heart failure or liver or renal dysfunction.

Metformin users should only sometimes indulge in alcoholic beverages. What “moderation” means is:

One drink daily for women
Men under the age of 65 are limited to two drinks per day, whereas men over 65 are allowed three.

However, you should talk to your doctor about your alcohol use since living a sober lifestyle may be best for your health.

What to Eat While Taking Metformin

Here are 5 items that one may include in their Metformin diet.

Complex carbohydrates: These sugars come from foods like fruits, vegetables, entire grains like brown rice, and bread made from whole grains. They include more fibre, which makes it harder for them to be digested. Consequently, the release of sugar into the circulation is slowed.

It is essential to monitor a person’s total carb intake if they consume complex carbs. This matters because carbohydrates have a direct impact on blood glucose levels. eating nothing when taking metformin

Encourage the intake of lean proteins such tofu, salmon, and turkey. While using metformin, lean protein

Healthy fats: Foods like fish, almonds, and olive oil are good sources of healthy fats.
Non-starchy vegetables: They might help to slow down the metabolism of carbohydrates. These vegetables could include leafy greens and broccoli, for instance. unsaturated fats
Consuming moderate amounts of fibre: Although it is advised to limit your intake of fibre, doing so might be beneficial. This is as a result of fiber’s role in controlling blood sugar levels. Between 25 and 30 grammes of fibre are typically consumed each day. eating nothing when taking metformin

Things to Steer Clear of While Taking Metformin

When using Metformin, taking a small number of medications may increase the risk of lactic acidosis. Therefore, if a person is taking any of the following medications, it is crucial to address this with the relevant doctor:

Corticosteroids like prednisone, diuretics like acetazolamide, antipsychotic drugs like chlorpromazine, anticonvulsants like topiramate, zonisamide, oral contraceptives, and antihypertensives like amlodipine

After taking this medication, a person must refrain from eating anything heavy in fibre. This is so that their concentration is decreased, since fibre may bind to medications. When massive amounts of fibre are ingested, metformin levels decline (more than 30 grammes per day).

Here are a few diet recommendations for people with diabetes:

Include carbohydrates from fruits, vegetables, and whole grains. Keep an eye on your carb consumption since it has a direct impact on your blood sugar.
Steer clear of foods high in trans and saturated fats. Have fish, nut, and olive oil fats in its stead.
A daily fibre intake of 25 to 30 grammes may help to control blood glucose levels.
Beware of salt. Try to limit your daily intake to 2,300 milligrammes or less.

Blood glucose levels are lowered with metformin. When it is not accompanied by a balanced, nutritious diet, it is far less effective. Consider limiting or eliminating items that raise blood sugar:

To enhance a person’s general health by getting the maximum benefit possible from any diabetic medication.

Major causes of elevated blood sugar include:

meals high in simple carbohydrates (sodas, candies, desserts)
refined sugars (white bread, white rice, pasta)

Choose complex carbohydrates instead, including brown rice and whole-grain bread. These carbohydrates have a lot of dietary fibre. They are thus more difficult for the body to process. The release of sugar into the circulation is slowed as a result. In addition

Make sure to include lean meats (such turkey, salmon, and tofu) and non-starchy vegetables on your plate at every meal. Broccoli and leafy greens are examples of them.

Should you hydrate well while taking this medication?

To help reduce any stomach or intestinal adverse effects that may appear during the first few weeks of therapy, metformin must be taken with meals. It is necessary to swallow the whole pill or extended-release tablet together with a full glass of water. Do not chew, shatter, or crush the pill.

What happens if someone taking metformin has glucose?

Food items are not prohibited while taking the medication. On the other hand, a nutritious diet is necessary to help control diabetes. The body would have to work harder to lower the blood sugar levels when a person consumed glucose plus metformin.

Are diabetics okay to drink cucumber water?

Cucumber may be a beneficial addition to a diabetic person’s diet in order to more effectively control blood glucose levels.

Does milk affect how metformin works?

Due to little baby exposure, metformin appears to be “safe” while nursing. The unusual concentration-time profile for the drug in milk suggests that passive diffusion is not the only mechanism by which metformin enters milk.

Is drinking coffee while taking Metformin safe?

The body breaks down caffeine to eliminate it. Metformin may slow down the body’s metabolism of caffeine. When used with caffeine, metformin may intensify both the benefits and drawbacks of caffeine.
