A condition where there is temporary weakness or paralysis in the facial muscle is called Bell’s palsy. What ultimately causes Bell’s palsy to occur is when the nerve that controls the facial muscles gets inflated, swollen or compressed. When a person gets attacked with this problem, his face will appear like it has been droopy and paralyzed. The person then will not be able to smile or close his eye of the side of face that has been affected.

There are many causes and risk factors. However, there is no definite cause of Bell’s palsy but it can help you understand the problem by knowing what are the things that might trigger the nerves to cause this problem:

Causes of Bell’s palsy:
The nerve that controls the facial muscles is called the seventh cranial nerve. Here are some probable causes:

There are viral and bacterial infections that can lead to Bell’s palsy are herpes simplex. In herpes, there are cold sores that an infected person gets and that can affect the nerves of the area that is affected by herpes.

HIV is another viral infected that damages the immune system of the body and if someone has HIV it can lead to nerve damage or can cause other nerves, including the facial nerves to inflate and cause Bell’s palsy.

Lyme disease is one such disease that is caused by bacterial infection and is caused by infected ticks and that can be one of the causes of Bell’s palsy.
Sarcoidosis happens when there are small collections of inflammatory cells in the body. Neurosarcoidoisis is what sarcoidosis can lead to Bell’s palsy by causing damage to nerves that control facial muscles.

Risk factors that can lead to causes of Bell’s palsy:
The risk of developing a condition of Bell’s palsy may increase if someone is pregnant, has diabetes, has an infection in the lungs, or has a family history of the same condition.
It is important to understand the causes and risk factors of Bells’s palsy to control it in case you have any of the above-mentioned causes and risks. The better you understand what may lead to the causes of Bell’s palsy, the easier it will be for you to know what may prevent it.

Another way to recognize the condition is by identifying the symptoms first. There are various symptoms of Bell’s palsy and before it leads to facial paralysis, you may identify and take necessary steps towards curing and treating it.
