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.
- Vomiting: Vomiting blood or severe vomiting.
- Fever: High fever (over 101.5F).
- Abdominal tenderness: Stomach tenderness to the touch.

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 allHey, I've been taking Follihair tablets for over a year now, and I've just picked up another year's supply. Do you think it's okay to keep using them for this long? Also, I've noticed that the ingredients have changed a bit. The old tablets had 10 mg of biotin, but the new ones only have 30 mcg, along with some other new vitamins and minerals. With such a big difference in biotin, do you think the new tablets will still work as well as the old ones? I'm mainly asking because biotin is supposed to be a key ingredient for hair growth, right?
Biotin is indeed an important ingredient for promoting hair growth, but the newly added vitamins and minerals in the new formulation may also contribute to overall hair health. It is advisable to continue using the new formulation and monitor any changes in hair growth or health. It is generally safe to use follihair tablets for an extended period of time, as they are commonly used for hair growth and hair health.

I've noticed some cut marks on my wrist that have turned quite dark and are looking pretty bad. I'm really concerned and wondering if there's anything I can do to help reduce these scars or lighten them up. It's really affecting how I feel about my appearance. Can you offer any advice or treatments that might work?
For treating dark and unsightly scars on your wrist, you can use a silicone gel such as Dermatix Ultra. Apply a thin layer of the gel on the scar twice daily. Additionally, you can also consider using a scar lightening cream like Mederma. Apply the cream on the scar once daily. Remember to follow the instructions on the packaging for best results.

I've been using Betnovate cream on my face for about a year, but then I found out it has steroids, so I stopped. Now my face seems way darker compared to the rest of my body. What can I do to fix this, and should I see a specific type of specialist? I'm really worried about how my skin looks.
