Why Am I Losing Hair at 30 ?


Hair goes through a constant cycle of growing and shedding.

Sometimes much of the head will be in the same cycle, so a large amount of hair comes out at once; new hair is growing in at the same time, but because hair falls out faster than it comes in, thin hair will be the result.

Usually within 6-12 months, the hairs will once again be out of cycle, so you will only lose about 100 hairs a day instead of thousands at a time.

Stress, whether physical or emotional, can cause the hairs to cycle all at once.
Another possible cause for hair loss is increased male hormone levels or unusual sensitivity of your hair follicles to normal amounts of male hormones.

All women produce some amount of the male hormone testosterone.

This is associated with a short growth phase, so hairs fall out more rapidly than they come in.

X rays during early pregnancy ??


X-rays can harm an unborn baby.

If a baby receives more than 5,000 millirads of radiation from x-rays before birth, the baby might have birth defects.

The x-rays might cause leukemia.

Most x-rays give much smaller doses of radiation than this.

For example, during an x-ray of the legs, only 1 millirad is absorbed.

Although only a small amount of radiation may be absorbed, x-rays should be avoided, especially in early pregnancy.
This is why x-ray technologists may ask when you had your last menstrual period before taking an x-ray.

X-ray studies are done during pregnancy only in urgent cases.

For example, you may have an x-ray if you have a broken bone, to check for pneumonia, or to look for kidney stones.

When taking an x-ray, the technologist should put a lead apron over you to protect the baby.


However, this may not be possible if the apron will interfere with the necessary views (for example, x-rays of the chest).

Ultrasound machines do not use radiation. Often an ultrasound scan can be done instead of an x-ray.
