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 allI've been using this Panderm Plus cream, and every time I go out, my skin seems to get darker, even though I put on sunscreen. I'm really thinking about stopping the use of this cream, but I'm not sure how to get my skin back to normal afterward. Do you have any advice on how I can handle this situation?
1. *Gradually taper off*: Don't stop using Panderm Plus abruptly. Gradually reduce the frequency and amount applied over 2-3 weeks. 2. *Replace with alternative creams*: Consult your doctor or dermatologist for alternative creams that are less likely to cause hyperpigmentation. 3. *Use sunscreen with high SPF*: Continue using a broad-spectrum sunscreen with high SPF (at least 30) and reapply every 2 hours. 4. *Wear protective clothing*: Cover your skin with clothing, hats, and umbrellas when going out. 5. *Consider vitamin C or niacinamide creams*: These creams may help reduce hyperpigmentation and promote skin brightening.

I'm really grateful for your helpful response last time. I'm happy with the service you provide for patients. I've got another question, though. My skin texture isn't great there's some acne left even though I'm on medication and seeing a dermatologist. Theres also some pigmentation. My previous dermatologist gave me SabiGlow cream for skin lightening and to help with the pigmentation. Do you think this will help lighten my skin? I've got a wheatish skin tone, and Im curious if it's safe to use. I also stopped using propyzole nf cream after reading your review. You suggested Cetaphil DAM cream, but my skin is oily. It gets a bit dry right after washing, but gets oily again soon after. Can I still use Cetaphil DAM cream with my oily skin?
Sabi-Glow cream can be effective for lightening pigmentation and improving skin texture, but make sure you use it under the guidance of your dermatologist and always wear sunscreen. For your oily skin, you may want to adjust your moisturizer. Cetaphil DAM could be too heavy, but you can try using a smaller amount or consider switching to a lighter moisturizer like Cetaphil oil-free or a gel-based option.
