Having a sensation of a fat lip generally is usually due to swelling, which generally occurs as a result of direct contact. Playing contact sports without any protection on your face can give you a fat lip, but the swelling is usually more complicated. In many cases, it may be a sign of a severer illness inside the body.

It is necessary to know the reasons for swollen lips. You can visit your dentist or doctor to discuss its treatment.
What are the causes of a swollen lip?
Trauma is by far the most significant reason for a swollen lip. The thin skin of the lip is quite sensitive, so it doesn’t resist the impact of contact. It can result in the blood rushing to the affected area, causing it to grow a little to form swelling. Fortunately, most cuts and bruises are treatable at home. You will need to analyze the swollen area. If there is no cut, you can apply ice to help reduce swelling. If the skin is broken, you may want to apply a clean, cold compress to control bleeding. You may want to refer to your doctor if bleeding doesn’t stop in 5-10 minutes after the impact.
Another common reason for swelling in lips is an allergy. A condition, known as allergic angioedema, is the most specific reason for swelling in the lips. This condition results in a histamine result in the body, leading to a buildup of fluids underneath the skin layer. The Mayo Clinic suggests allergic angioedema to be a result of food allergies. It will be hard for you to realize that you have a food allergy until to eat something that causes a burning sensation on your lips, mouth, and throat. If it is a mild allergic reaction, you may want to control it through over-the-counter medication, such as Benadryl. This medicine will control your body’s response to antihistamines.

An infection can also be a reason for the swollen lip. Such an infection inflames and irritates the skin tissues on the lips, causing swelling. If you have had a cut on your lip, and it feels swollen, inflamed, and hot to touch even after a few days, it may be a sign of infection. Infection occurs usually when healing wounds and blisters get filled with bacteria, resulting in the healing process to halt or even reverse. Touching a healing wound can cause inflammation or infection, which can result in a swollen lip.
Various chemical reactions inside the body can result in bunds and wounds, especially in sensitive tissues, such as lips. Such conditions can result in blistering, swelling, and overall discomfort. If there is only swelling, you may want to use a cold compress to find some relief. You may need medical attention to treat such an issue. The doctors commonly suggest antibiotics for treatment in this regard.
The key to preventing or treating swollen lips is to stay safe from impacts and practice good overall hygiene. You do not want to have a bacterial infection because it can worsen to cause greater discomfort in the lip area along with swelling.
