Understanding Metformin

Metformin is a cornerstone treatment for type 2 diabetes, working primarily by decreasing glucose production in the liver. It’s especially favored for its effectiveness and established history. However, understanding its role in diabetes management is only one piece of the puzzle.

Common Side Effects

Many metformin users experience side effects, with gastrointestinal disturbances being the most prevalent.

Gastrointestinal Issues

• Nausea and Vomiting: Frequently reported, especially at treatment onset.
• Diarrhea: Can occur during initial dosage or after long-term use.
• Stomach Pain: May include bloating or discomfort.

These symptoms often improve over time. Read more about side effects here.

Nutrient Absorption

Metformin can hinder nutrient absorption, particularly affecting vitamin B12 levels, which over time can lead to deficiency. Symptoms include fatigue, weakness, and nerve damage.

For further details, the Diabetes UK website provides extensive resources.

Serious Side Effects

Although rare, serious side effects require prompt medical attention.

Lactic Acidosis

This potentially life-threatening condition involves an accumulation of lactic acid in the bloodstream. Symptoms include:

• Weakness
• Breathlessness
• Cold feet and hands

For a deep dive, Harvard Health’s article on lactic acidosis can be insightful.

Vitamin B12 Deficiency

A long-term consequence of metformin use can lead to vitamin B12 deficiency, possibly resulting in nerve damage and cognitive impairment.

The Mayo Clinic offers more information on vitamin B12 deficiency.

Managing Side Effects

Proactively managing side effects involves a combination of strategies:

• Regular Monitoring: Regular blood tests can catch deficiencies early.
• Dietary Adjustments: Increasing dietary intake of vitamin B12 or supplements can mitigate deficiencies.
• Gradual Dosage Increment: Introducing metformin slowly to the system may reduce gastrointestinal disturbances.

Discuss any concerns with a healthcare provider, as individual responses to medication can vary.
