What to do if my MCV and MCH are low after taking metformin and I'm feeling suffocated?

When you have low MCV (mean corpuscular volume) and low MCH (mean corpuscular hemoglobin), your blood test results suggest microcytic anemia, which often indicates iron deficiency. This could be caused by metformin use, as it may lead to vitamin B12 malabsorption, but it’s more directly associated with low iron levels. Feeling suffocated or short of breath can be linked to anemia because your body might not be getting enough oxygen. Given these results and symptoms, it’s important to address both the immediate sensation of suffocation and the underlying cause. Firstly, if you’re experiencing significant shortness of breath or feel faint, you should seek medical attention promptly, as these can be serious symptoms. To understand and manage the underlying condition, it would be wise to get your iron levels checked, including serum ferritin or transferring saturation, along with vitamin B12 levels. If iron deficiency is confirmed, your doctor may recommend iron supplementation, either orally or, in some cases, intravenously, depending on severity. Vitamin B12 levels should also be addressed if they’re low, which can involve supplements or dietary adjustments. Also, review your diet to ensure adequate intake of iron-rich foods, such as red meat, leafy greens, and iron-fortified cereals. Consider a balanced multivitamin, but consult with your healthcare provider before starting any new supplement. Importantly, don’t make any medication changes with metformin without consulting your doctor, as it can influence your diabetes management. Regular follow-ups to monitor blood levels and symptom relief are essential. Always prioritize getting medical assessment sooner rather than later if your symptoms are worsening.
