Introduction
Enlarged submandibular lymph nodes may be caused by lifestyle habits, reactive hyperplasia, tonsillitis, lymphadenitis, systemic lupus erythematosus (SLE), and other conditions. Improvement can be achieved through lifestyle modifications and medication. Unhealthy lifestyle habits, such as chronic sleep deprivation and an unbalanced diet, may lead to decreased immune function, thereby increasing the risk of lymph node enlargement.

Swollen lymph nodes under the jaw may be caused by lifestyle habits, reactive hyperplasia, tonsillitis, lymphadenitis, systemic lupus erythematosus (SLE), and other conditions. Improvements can be achieved through lifestyle modifications, medication, and other methods.

1. Lifestyle habits: Unhealthy lifestyle habits, such as chronic late-night sleep and unbalanced diet, may lead to a decline in the body's immunity, thereby increasing the risk of swollen lymph nodes. It is recommended to improve lifestyle habits, maintain a regular schedule, eat a balanced diet, and avoid consuming spicy or irritating foods.

2. Reactive hyperplasia: When exposed to external stimuli or changes in the internal environment, lymph nodes may mount an immune response, causing an increase in lymphocytes and resulting in swollen lymph nodes. This swelling is usually temporary and does not typically accompany other symptoms. It generally does not require specific treatment and can improve on its own.

3. Tonsillitis: Tonsillitis may be associated with factors such as exposure to cold, environmental conditions, and infections. The resulting inflammation can activate immune cells in the local lymph nodes, causing the lymph nodes to enlarge. Symptoms may include fever, redness, swelling, and pain in the affected area. Patients may follow medical advice to use medications such as Compound Honeysuckle Granules, Amoxicillin Capsules, Roxithromycin Tablets, and others for treatment.

4. Lymphadenitis: Lymphadenitis is usually caused by bacterial infections. Bacteria may enter the lymph nodes via infections in areas such as the mouth or throat, triggering an inflammatory response and causing swollen lymph nodes. Symptoms typically include pain, redness, swelling, and fever. Patients may follow medical advice to use medications such as Cefradine Capsules, Cephalexin Capsules, Clindamycin Hydrochloride Tablets, and others.

5. Systemic lupus erythematosus: This condition may be related to genetic and environmental factors. The immune system mistakenly attacks the body's own tissues, potentially affecting multiple organs, including the lymph nodes. It may be accompanied by systemic multi-organ damage manifestations, such as joint pain, rashes, photosensitivity, oral ulcers, and more. Patients may follow medical advice to use medications such as Prednisone Acetate Tablets, Clobetasol Propionate Cream, Danazol Capsules, and others for improvement.

If discomfort symptoms occur, it is recommended to seek timely medical consultation at a hospital, clarify the condition, and follow medical instructions for treatment to avoid delaying the progression of the disease.

Which tumors are prone to lymph node metastasis?
Tumors that are prone to lymph node metastasis generally include breast cancer, gastric cancer, lung cancer, colorectal cancer, and thyroid cancer. Breast cancer cells easily invade surrounding lymphatic vessels and can metastasize early to ipsilateral axillary lymph nodes. In some patients, enlarged axillary lymph nodes are already present at the time of diagnosis, and in advanced stages, metastasis may further spread to lymph nodes above the clavicle, internal mammary region, and other areas.

Is it normal for submandibular lymph nodes to remain swollen without subsiding?
Swollen submandibular lymph nodes that persist without resolution may represent a benign condition if they result from a previous acute infection or chronic inflammation, especially when no other symptoms are present and the swelling remains stable over time. However, if the lymph nodes continue to enlarge, become painful, or are accompanied by systemic symptoms, this is more likely indicative of an abnormal condition. Medical evaluation should be sought promptly if the swelling lasts longer than 2 weeks, exceeds 1 cm in diameter, or presents with other unusual features.

What can I eat to help reduce swollen lymph nodes?
Food itself does not have the direct function of dispersing lymph nodes. However, a balanced diet can assist the body's self-repair and enhance immunity. Patients with lymph node issues should consume foods rich in high-quality protein, vitamin-rich vegetables, high-fiber fruits, immune-boosting mushrooms, and light, easily digestible staple foods. If rapid enlargement of lymph nodes, fever, or increased pain occurs, seek immediate medical attention at the appropriate specialty clinic.
