Hi Asha, Welcome to HealthCare Magic Forum
Firstly let me explain to you what Bell's Palsy
is. Its a one - sided paralysis
of the face, due to inflammation leading to swelling and compression of the facial nerve
, which supplies that part of the face. There is no one particular reason as to what can cause it, but mostly commonly implicated is a viral infection, affecting the nerve and remains dormant unless exposed to some sort of stressful situation, when the virus gets reactivated.
You shouldn't worry much as its a self-limiting disease, it'll subside over time and you should be able to recover your normal facial functions. Medications and physiotherapy
should suffice, but I still advise to you consult a neurologist
in this matter. As far as your weight is concerned, you should consult a dietician, get your diet right and exercise well.
