This posting is inspired from the recent advice of my nephrologist to stop taking metformin for my diabetes as it is contraindicated to my CKD. I was also prescribed sodium bicarbonate tablets.
While Metformin is a generally safe and effective medication for type 2 diabetes, men may experience certain side effects.
Common side effects
- Digestive issues: Nausea, vomiting, diarrhea, stomach discomfort, gas, heartburn, and loss of appetite are common, especially when first starting the medication.
- Headache: WebMD notes this is a common side effect.
- Metallic taste: A change in how things taste or a metallic taste in the mouth can occur.
- Weakness or fatigue: Feeling unusually weak or tired is a possible side effect.
Potential effects on male hormones and reproductive health
- Testosterone levels: Some research suggests Metformin can lower testosterone levels in men with type 2 diabetes, which could affect erections and libido. However, other studies indicate that Metformin may improve blood flow and potentially help with erectile dysfunction (ED) in some cases.
- Erectile dysfunction (ED): While Metformin doesn't directly cause ED, diabetes itself is a significant risk factor, making it crucial to discuss any concerns with a doctor to determine the underlying cause.
- Male fertility: Some studies have raised concerns about the potential effects of Metformin on male reproductive health and fertility, particularly if exposure occurs during fetal development.
Rare but serious side effects
- Lactic acidosis: This is a rare but life-threatening condition caused by a buildup of lactic acid in the blood. Symptoms include extreme tiredness, weakness, nausea, vomiting, stomach pain, decreased appetite, rapid breathing or shortness of breath, dizziness, lightheadedness, fast or slow heartbeat, and feeling cold in the hands or feet. If you experience these symptoms, seek immediate medical attention.
- Vitamin B12 deficiency: Long-term Metformin use can potentially lead to low vitamin B12 levels. Verywell Health emphasizes the importance of monitoring B12 levels, as deficiency can cause serious neurological damage and other problems.
In Addition my nephrologist also prescribed sodium bicarbonate tablets because of my CKD resulting to metabolic acidosis and mild hyperkalemia ( high potassium levels).
Sodium bicarbonate tablets are primarily used as an antacid to relieve symptoms of acid reflux, such as heartburn, indigestion, and sour or upset stomach
. They work by neutralizing excess stomach acid. Sodium bicarbonate can also be used to treat or prevent excess acid in the blood or urine in certain conditions. However, it's crucial to understand that while sodium bicarbonate can offer quick relief for occasional heartburn, it's not a long-term solution, according to Kaiser Permanente. Excessive or prolonged use can lead to side effects like bloating, gas, electrolyte imbalances, and potentially rebound acidity.
Sodium bicarbonate may also be used in more serious medical conditions under a healthcare provider's guidance, such as:
- Metabolic acidosis: Sodium bicarbonate can be used to treat metabolic acidosis, a condition where there's too much acid in the body, often associated with kidney disease or severe dehydration.
- Hyperkalemia: In cases of severe hyperkalemia (high potassium levels), sodium bicarbonate may be administered to help shift potassium back into cells.
- Certain drug toxicities: In some instances of drug toxicity, such as with barbiturates or toxic alcohols, sodium bicarbonate can help with urine alkalinization, aiding in drug excretion.
