I'm a bit worried because Ive been taking vitamin B12 injections and supplements due to a deficiency. Initially, my B12 level was 212, but now its shot up to 2000 in my latest lab test. Is having a vitamin B12 level that high dangerous, and how can I bring it down quickly? Sometimes I feel my body shakingcould that be because my B12 levels are too high?

Having a vitamin B12 level above 2000 is considered high, and it may lead to symptoms such as body shaking. To reduce the high level of vitamin B12 quickly, you should stop taking any B12 supplements or injections and consult with your healthcare provider for further guidance. They may recommend adjusting your dosage or frequency of B12 intake. In the meantime, you can focus on a diet that is low in vitamin B12-rich foods such as meat, fish, and dairy products. Make sure to stay hydrated and maintain a healthy lifestyle. If your symptoms persist or worsen, seek medical attention promptly.

Can I drink an ORS solution once or twice daily for rehydration? Is this safe, or could it cause problems for me later on? Should I be using something else like glucose instead since my doctor mentioned I've lost a lot of water in my body? What do you recommend?

ORS can be taken once or twice daily for rehydration, especially if you're experiencing dehydration. It helps replenish lost electrolytes safely. However, glucose alone is not as effective for rehydration since it lacks electrolytes. Stick to ORS for better hydration, but consult your doctor if you have any concerns.
