The term "submandibular lymphadenopathy" describes swollen lymph nodes under the mandible (lower jaw). Infection is typically indicated by hot, swollen, sensitive, and pliable lymph nodes that are also accompanied by other symptoms.
Additionally, infections of the upper respiratory tract, tonsils, sinuses, or from mononucleosis and cut-scratch disease can cause submandibular lymphadenopathy.
<h3>What is lymph node ?</h3>
A small bean-shaped element of the immunological system. White blood cells called lymphocytes, which are found in the lymph nodes of the body, help the body fight off disease and infection. They remove materials that the lymphatic fluid does not filter. There are thousands of lymph nodes all across the body.
- Immune cells are produced in lymph nodes to help in the fight against infection. They also filter the lymph fluid to remove contaminants like pathogens and cancerous cells. They can swell as a result of swelling, an abscess, cancer, and—most commonly—inflammation.

According to the article I've read in the website of Harvard Health Publishing (Harvard Medical School), the causes of overweight or obesity have been implicated by more than 400 different genes. Genes provide overweight in so many ways like metabolism, appetite, cravings, distribution of fats, and stress eating. Although it depends on one person to another person. Researchers have said that 25% of predisposition to be overweight is accounted to genes, while 70%-80% for genetic influences. These are just some of the reason how much of your weight depends on your genes:
-For much of your life, you have been overweight
-Overweight is seen on your parents or relatives, your likelihood to be developing obesity is as high as 80% if both of your parents are overweight
