Why is my sudden hair loss ?

This may also be associated with the dandruff and hair fall. I suggest that you consult a dermatologist who will offer the right diagnosis and treatment protocol.

It appears that you are experiencing symptoms of oral thrush, a condition that causes your tongue to be covered in white. Smoking is one of the major causes of this disease, and so is drinking alcohol or having a weak immune system. The most effective way to deal with it is to reduce smoking and alcohol intake, as well as maintain good oral hygiene. Additionally, drinking more water can also help.

The marks are the result of the body's response to the mosquito's saliva. They may gradually diminish by themselves over time, however, you can also apply over-the-counter creams with ingredients such as hydroquinone or vitamin E that will help in the process.

Hemorrhoids cause­ itchiness. They're puffy ve­ins close to the rectum. Along with itching, a pain or bulge­ may form there. Sitting a long while, pushing hard during bowe­l movements, or being ove­rweight can worsen them. For itching re­lief, use soft wipes, take­ warm baths, don't scratch. Always keep that area tidy and arid.
