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?

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.

I'm dealing with saggy and heavy breasts and I'm a bit worried about it. Can you recommend a really good cream for breast tightening and firming?

Consider using creams containing ingredients like vitamin C, vitamin E, retinol, or plant extracts like saw palmetto, or firming peptides, such as Naturaful Breast Enhancement Cream, Mustela Breast Firming Cream, or UpCurve Breast Firming Cream, but keep in mind that creams may have limited effectiveness and individual results may vary; for more pronounced results, consider consulting a plastic surgeon or dermatologist about non-surgical or surgical options.

I'm really struggling with ingrown hairs every time I shave or use any hair removal method. It's so tough trying to get rid of them, and on top of that, I've got these strawberry legs. Even after waxing, my pores still show up, and it's been like this for years. I'm super embarrassed about how my legs look. I live in Bangalore and would really appreciate any advice you have. What can I do to improve this situation?

That needs Physical examination,visit Dermatologist for the same and appropriate management

I've noticed this small hole in my skin, kind of looks like a needle prick. It's not red, but it feels tender to touch, and there's a bump under the skin. When I first saw it, the area was warm. There's no pus, but the bump feels pretty hard. It's not really painful, but it does hurt if I press on it. I'm a bit worried. Do you think this is something I should check out?

That could be insect bite or so..,no need to worry it will subside in a day,if it starts itching or becoming worse,visit your doctor for evaluation and appropriate treatment,you dont attempt to scratch it or squeeze it.
