Is Your Metformin Working? Look for These Signs

Metformin is a medication commonly prescribed to individuals with type 2 diabetes, polycystic ovary syndrome (PCOS), and other metabolic disorders. It works by reducing the amount of glucose produced by the liver and improving the body’s sensitivity to insulin. While taking metformin, it is important to monitor the effectiveness of the medication to ensure that it is properly managing the condition. In this article, we will explore the signs metformin is working and discuss how to determine if the medication is effective in managing the individual’s health condition.

Why do people take Metformin?

Metformin is a medication commonly prescribed to individuals with type 2 diabetes, a condition characterised by high blood sugar levels due to the body’s resistance to insulin or insufficient insulin production. Metformin works by reducing the amount of glucose produced by the liver and improving the body’s sensitivity to insulin, which helps to lower blood sugar levels.

In addition to managing diabetes, metformin is also prescribed for individuals with polycystic ovary syndrome (PCOS), a hormonal disorder that can cause insulin resistance and high blood sugar levels. Metformin can help regulate menstrual cycles, improve fertility, and reduce the risk of developing diabetes in women with PCOS.

What are the side effects of metformin?

Like all medications, metformin can cause side effects, although not everyone experiences them. Some of the common side effects of metformin include:

  • Gastrointestinal problems such as diarrhea, nausea, vomiting, abdominal discomfort, and indigestion
  • Headache
  • Lactic acidosis, a rare but serious side effect that can occur when too much lactic acid builds up in the body
  • Hypoglycemia, especially if the medication is not taken as prescribed or if the individual has other medical conditions
  • Decreased vitamin B12 absorption, which can lead to anaemia and neuropathy if left untreated
  • Taste disturbances
  • Skin reactions, such as rash or itching.

Signs metformin is working

Here are some signs that metformin is working to manage diabetes or other health conditions:

Lower blood sugar levels 

Metformin helps to lower blood sugar levels by reducing the amount of glucose produced by the liver and improving insulin sensitivity. Regular monitoring of blood sugar levels can help determine if metformin is effectively managing the condition.

Improved HbA1c levels 

HbA1c is a measure of average blood sugar levels over the past two to three months. Metformin can help to lower HbA1c levels, which indicates better long-term blood sugar control.

Weight loss 

Some individuals may experience weight loss while taking metformin. This is because metformin can reduce appetite and increase feelings of fullness, which may result in fewer calories consumed.

Regular menstrual cycles 

In women with PCOS, metformin can help regulate menstrual cycles, improve fertility, and reduce the risk of developing diabetes.

Improved lipid profile 

Metformin can help to improve lipid profiles by reducing triglyceride and low-density lipoprotein (LDL) cholesterol levels.

Improved insulin sensitivity

Metformin improves the body’s sensitivity to insulin, which allows for better glucose uptake by the body’s cells.

How long does it take for metformin to start working?

Metformin usually starts working immediately after the first dose, but it may take several weeks to see the full effect of the medication. The time it takes to see the effect of metformin varies depending on the individual’s health condition and other factors.

For individuals with type 2 diabetes, blood sugar levels may start to improve within a few days to a week of starting metformin. However, it may take several weeks or months to see the full effect of the medication on HbA1c levels, which reflects the average blood sugar levels over the past two to three months.

What are the benefits of taking metformin?

Metformin has several potential benefits for individuals with certain health conditions, including:

  • Improved blood sugar control

Metformin is primarily prescribed to individuals with type 2 diabetes to improve blood sugar control. It works by reducing the amount of glucose produced by the liver and improving the body’s sensitivity to insulin.

  • Lower risk of developing diabetes

In individuals with prediabetes, metformin may help prevent or delay the onset of type 2 diabetes.

  • Improved cardiovascular health 

Metformin has been shown to have cardiovascular benefits, such as reducing the risk of heart disease and stroke, in individuals with diabetes.

  • Improved fertility in women with PCOS 

Metformin can help regulate menstrual cycles, improve fertility, and reduce the risk of developing diabetes in women with PCOS.

  • Potential weight loss 

Some individuals may experience weight loss while taking metformin. This is because metformin can reduce appetite and increase feelings of fullness, which may result in fewer calories consumed.

  • Reduced risk of certain cancers 

Some research suggests that metformin may have potential benefits in reducing the risk of certain cancers, such as breast, colorectal, and prostate cancer. However, further research is needed to determine the efficacy of metformin for cancer prevention.

What is the maximum dosage of metformin?

The maximum dosage of metformin varies depending on the individual’s health condition and other factors. In general, the maximum recommended daily dose of metformin for adults is 2,550 mg per day, although some individuals may require higher doses under the guidance of a healthcare provider.

For individuals with type 2 diabetes, the usual starting dose of metformin is 500 mg or 850 mg once daily with meals, and the maximum dose is typically 2,000 to 2,550 mg per day in divided doses. However, some individuals may require higher doses to achieve optimal blood sugar control.

For individuals with polycystic ovary syndrome (PCOS), the usual starting dose of metformin is 500 mg or 850 mg once daily with meals, and the maximum dose is typically 1,500 to 2,000 mg per day in divided doses.

Does metformin cause weight loss?

Metformin can cause weight loss in some individuals by reducing appetite and increasing feelings of fullness, although not everyone experiences this side effect. It is not a weight loss medication and should not be used for that purpose alone.
