Aminu Danjuma Liadi , you claim to be in Medical School, yet here you are on Quora asking questions whose answers can be found in your institutions library.
With a little curiosity, and diligence, both which are mandatory traits in a medical student, you should be able to come up with an answer by yourself! If you’re lazy, just ask your medical seniors or medical lecturers.
But I’m going humor your lazy ass.
There are multiple reasons to why a person may have receding hairline so early in life. For the sake of simplicity and because I’m going out for lunch soon I’m just going to state the common ones.
First, genetics. That’s self explanatory right there so I don’t think I have to elaborate on this.
Next, we have the continuous excessive production of dihydrotestosterone ( DHT ) , which is a male hormone. In med school, if you haven’t learnt it already, you’d know that once 5-Alpha-Reductase acts on testosterone, it will produce DHT which kick start your puberty and secondary male sexual characteristics.
Normally, DHT should taper out and slowly cease production as you grow older. But in some cases, production persist and excessively. Over time it deposits in parts of your body, and in this case, namely your hair follicles. Over time, too much of it accumulates and kills of the hair follicle leading to your receding hairline.
As for the other reasons, get your ass to your library and start reading.
Next , gum bleeding when you brush ??
In my practice, the most common cause would be inflammation of the gum margins also known as gingivitis. And what cause gingivitis ? Plenty of reasons, most common cause is poor oral hygiene.
So get your ass a dentist and have your oral condition checked out and maybe cleaned as well.
Also, I checked out your profile and frankly, some questions are disturbing. Like What if I attack the UN General Assembly and take all world leaders and other members hostage, would the world be in my palms?
Why am I sexually attracted to little girls and even babies?
