Why Can Taking Both Medicines Matter?
The main concern is their potential combined effect on vitamin B12 levels.
Vitamin B12 is essential for healthy red blood cells, normal nerve function, and DNA production. The body obtains it from foods such as meat, fish, eggs, dairy products, and fortified foods.
Metformin can interfere with vitamin B12 absorption. Omeprazole reduces stomach acid, which helps the body release vitamin B12 from food. When both medicines are taken over a prolonged period, some patients may have a greater risk of developing a deficiency.
Research has investigated this association, although the size of the additional risk varies between studies. Not everyone taking both medicines will develop low vitamin B12 levels.
The important point is that this combination may warrant closer attention to vitamin B12 status, particularly in people with additional risk factors.
What Are the Symptoms of Vitamin B12 Deficiency?
Vitamin B12 deficiency can develop gradually, and symptoms may be mistaken for tiredness, aging, or other medical problems.
Possible warning signs include:
1. Unusual Tiredness or Weakness
Low vitamin B12 can contribute to anemia, which may cause persistent fatigue, weakness, or reduced energy
