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

  1. Stay hydrated: Drink plenty of water.
  2. Avoid triggers: Steer clear of spicy, fatty, or heavy foods.
  3. Over-the-counter relief: Try antacids or acid reducers like Tums, Rolaids, or Zantac.

When to Seek Medical Attention

  1. Severe pain: Unbearable or worsening pain.
  2. Vomiting: Vomiting blood or severe vomiting.
  3. Fever: High fever (over 101.5F).
  4. Abdominal tenderness: Stomach tenderness to the touch.

For your tests related to hair fall, here are some key points to know about fasting requirements:

  1. 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.

  2. Complete Blood Count (CBC): No fasting is required for a CBC test.

  3. 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.

I'm struggling with a Tinea Cruris infection around my thighs and back. I used lulifin ointment with tenovate before, and it seemed to help at first, but after a month, the infection came back in the same spot. Now I'm using ZoleF ointment. Can you suggest any creams or medicines that could provide a permanent solution for this issue?

For Tinea Cruris infection, it is important to use antifungal medications consistently to prevent recurrence. In addition to Zole-F ointment, you can consider using Terbinafine cream (brand name Lamisil) twice daily for 2-4 weeks. It is important to continue the treatment for the full duration even if the symptoms improve to prevent the infection from coming back. Additionally, keeping the affected areas clean and dry, wearing loose-fitting clothing, and avoiding sharing personal items can help prevent reinfection.

I'm looking for a permanent solution for skin whitening. I'm tired of using all these temporary fixes and would love to know if there's a lasting and effective method to get the result I'm looking for. Can you help guide me?

For permanent skin whitening, you can consider using topical creams containing hydroquinone in combination with tretinoin and corticosteroids. One such effective brand is Tri-Luma cream. It is usually applied once daily in the evening. However, it is important to use this medication under the guidance of a healthcare professional, as prolonged use can have side effects. Additionally, using sunscreen with a high SPF is crucial to prevent darkening of the skin due to sun exposure.
