Do I really need to fast before getting tests for vitamin B12, vitamin D, CBC, and thyroid? I was told to get these because I'm dealing with hair fall, but I'm not sure if fasting is necessary. Can you clarify this for me?

The needle-like stomach pain could be due to gas, acid reflux, food poisoning, or stress. To alleviate the discomfort:
Self-Care
- Stay hydrated: Drink plenty of water.
- Avoid triggers: Steer clear of spicy, fatty, or heavy foods.
- Over-the-counter relief: Try antacids or acid reducers like Tums, Rolaids, or Zantac.
When to Seek Medical Attention
- Severe pain: Unbearable or worsening pain.

For your tests related to hair fall, here are some key points to know about fasting requirements:
-
Vitamin B12 and Vitamin D tests: Generally, you do not need to fast before these blood tests. They can be done at any time of the day.
-
Complete Blood Count (CBC): No fasting is required for a CBC test.
-
Thyroid function tests: These also do not require fasting.
It's always a good idea to follow any specific instructions given by your healthcare provider or the lab. If you are taking any medications or supplements, mention them before the test.
If you have any other concerns or symptoms, discussing them with your doctor will help tailor the testing and treatment plan effectively.

View allI've just started taking medication for hair treatment since early September 2017 and I've come across some stuff about potential side effects. I'm kinda worried because some articles I read online are making me anxious. Are these side effects common for everyone, or is it just a few cases?
Continue same treatment.

I'm having issues with my tongue the skin is peeling, it's really painful, and I can't eat anything. Could you recommend any medicine for this? Do you think those Vitamin C chewable tablets would be helpful?
Could be due to a condition called oral mucositis. Vitamin C chewable tablets may not directly help with this issue. I recommend using a topical oral gel containing a local anesthetic like lidocaine to help with the pain and a mouthwash containing a mild antiseptic like chlorhexidine gluconate to prevent infection. Additionally, you can take over-the-counter pain relievers like acetaminophen for pain relief. If the symptoms persist, please consult a doctor for further evaluation and management.

I'm curious if there's any link between dandruff and masturbation. I've noticed that when I do masturbate during the week, I end up with a lot of dandruff in my hair, but if I don't, there's less dandruff. It's brown in color. This didn't happen before I started masturbating, but now it's becoming an issue. What could be going on here?
Dandruff in hair is usually caused by a fungal infection called Malassezia. Masturbation does not directly cause dandruff. However, stress and hormonal changes associated with sexual activity may contribute to dandruff flare-ups in some individuals. To address the dandruff issue, you can try using an anti-dandruff shampoo containing ketoconazole or selenium sulfide. Use the shampoo at least twice a week, leaving it on for 5-10 minutes before rinsing off. If the problem persists, consult a dermatologist for further evaluation and treatment.
