Swollen glands are usually a sign of an infection, and will normally go down within two or three weeks. The NHS explains that the lymph glands are small lumps of tissue that contain white blood cells, and are one of the ways in which the body fights off infection. If they encounter bacteria or viruses, the glands swell up in response.
The glands make up the endocrine system and are found on each side of the neck, under the chin, in the armpits, and around the groin. When they are swollen, they may feel painful and tender to touch.
A healthy endocrine system is important for many aspects of growth and development. There are several different types of glands: the thyroid and parathyroid glands are in the neck; the adrenals are above the kidneys, and the pancreas is behind the stomach.
The most important gland is the pituitary gland which is located in the brain. It controls the functioning of the other glands, and produces essential hormones such as prolactin in females, which aids the production of breast milk. It also plays a major role in regulating blood pressure and water balance.
What are the most common causes of swollen glands?
The most common causes of swollen glands include a cold or a throat infection. The majority of the time, the infection is fairly minor and will resolve itself within two to three weeks. Doctors may advise you to drink plenty of fluids, rest, and if necessary, take over-the-counter medications such as Solpadeine Plus or paracetamol.
When should you worry about swollen glands?
If after two weeks, your glands have not returned to their usual size, feel hard and do not move when pressed, or are getting bigger, you are advised to consult a GP. If you have night sweats or a very high temperature, or unexplained weight loss, you are also advised to contact your GP.
If there is no obvious sign of infection and you otherwise feel your usual self, then you are should also see a doctor. Occasionally, there may be a more serious infection or other cause for swollen glands.
Tuberculosis (TB) is a contagious bacterial infection that spreads to the lungs. Common symptoms include swollen neck glands, night sweats, loss of appetite, high temperature, and tiredness and fatigue. It can usually be cured with antibiotics, but anyone with persistent symptoms is advised to self-isolate until they are given the all clear by a doctor.
Sometimes, swollen glands may be a sign of a disorder of the immune system. For example, in conditions such as lupus, rheumatoid arthritis, or HIV, the immune system starts to attack the body’s tissues.
Swollen glands may also occasionally be a sign of cancer, which is why it is important to see a GP if your symptoms do not clear up or become worse after two weeks, or are accompanied by other symptoms such as night sweats, unexplained weight loss, or are firm and don’t move when you touch them.
