Lymph nodes: what inflammation says

 

At any time of the year, our body must fight against various bacteria and viruses that attack the immune system of adults and children.. One of the main symptoms of this struggle may beswollen lymph nodes, the main advocates of health. About how the human lymphatic system works and what the inflammation of the lymph nodes signals, we will tell you today in our material.

We get acquainted with the concept

The immune system protects the bodyinfection in several stages, and one of the lines of protection islymphatic system. It is through the work of the lymphatic system that infections are prevented from entering the body - bacteria and viruses. The main barrier to infection isThe lymph nodes.

The lymph nodes- unique biological filters through which lymph flows, bringing infection and foreign particles into the body, in response to whichlymph nodes are enlarged. Also in the lymph nodes ripenlymphocytes, protective cells that are actively involved in the destruction of foreign substances and cells.

The size of a healthy lymph node is no more than a pea, soft, homogeneous, mobile,About 500 of them are in the body.: in the arms and legs, internal organs, head and neck. Speaking as a kind of “sensor” of the foci of penetration and progression of infection, some lymph nodes are located separately, and in the region of the neck, armpits and groin - groups. Such localization allowsprevent viruses and bacteria from entering the tissues of the internal organswhere reproduction of aggressive agents is extremely favorable environment.

Why do lymph nodes grow?

Mainthe function of the lymph nodes is to fight infection, filtering viruses and other negative components of the environment.

When for this fightneed a large number of lymphocytesthey startform intensivelywithin lymph nodesnodes are increasing in sizewith it ofteninflammation occurs.

In this way,increasedandInflamed lymph node is an indicator of the pathological processin the body.

More oftenan increase in the size of the lymph node is local and short-lived- This is the reaction of the body’s immune defense against infection, by coping with which the lymph node will return to its original normal state.

By signslymph node inflammationare:

If, in addition to all the above signs, redness of the skin is observed, and painful sensations increase, then we can talk aboutlymphadenitis.

Lymphadenitislymph node inflammationwhich can be specific and nonspecific, purulent and non-purulent, acute and chronic, affect one or more lymph nodes.

Allotseveral major causes of inflammationlymph nodes:

  • local infection of a bacterial or viral nature (staphylococcus or streptococcus, diphtheria, rubella, cat scratch disease, and others);
  • generalized infection that affects the entire body (tuberculosis, typhoid, some skin diseases, cytomegalovirus, rubella, chickenpox, infectious mononucleosis);
  • connective tissue disease (arthritis, systemic lupus erythematosus);
  • oncological diseases;
  • hypersensitivity of the body;
  • granulomatosis.

There is no causeless increase and inflammation of the lymph nodes.therefore it is very important to find the reason why this happened. Prompt the reason may be the place in which the lymph nodes are enlarged. Most often, the problem has arisen in the organ, which is located next to the inflamed lymph node, but this is not always possible to find out right away.

Our forumwoman tellsVasoztells:“In a child, the lymph nodes on the back of the head grew, hurt, itched, just like bumps such two symmetrical. We went to the doctor, passed a bunch of tests, and while 4 days waiting for the results, the painful sensations disappeared, it doesn't hurt much, but they are all the same in size. The doctor, already with the results of the tests, said that perhaps we have such a type of constitution or the body reacted to some very toxic blackflies. He also said that there may be a virus and sent to pass tests for cytomegalovirus and Epstein-Barr. Waiting for results. "

Soswollen lymph nodes in the neckmay signal colds, sore throat, laryngitis, respiratory diseases, adenoiditis, tooth infection or teething, andparotidare increasingdue to eye diseases, infections of the middle and outer ear, otitis.

The reasonincrease in axillary lymph nodesThere may be an organism reaction to vaccination, hand skin infections or cat scratch disease - benign lymphoreticulosis. Its pathogen is the bacterium Bartonella, which lives in the body of pets through bites and scratches enters the child’s body, causes local inflammation and an increase in lymph nodes.

Chest lymph nodesand the roots of the lungs react to a pulmonary infection, the nodes of the abdominal cavity - to problems in the stomach and intestines,inguinalare increasingdue to the urinary system disease

butonly a doctor can make a definite diagnosisIt is the specialist who must find the cause of the lymph node enlargement and prescribe the appropriate treatment

Pediatrician of the clinic “Dobrobut” Babiy Galina Vasilyevna tells: “Lymph nodes are an accumulation of certain leukocyte cells (lymphoitis) that are responsible for immunity. Accordingly, in the presence of "danger" of any nature in the body, lymphocytes begin to actively deal with it,and since the majority of “foreign agents” migrate in the lymphatic channel, one way or another they get into the lymph nodes, where lymphocytes fight intensively with them, as a result of this an increase in lymph nodes occurs. Lymph nodes - occipital, anteroposterior and posterior cervical, mandibular, and behind-the-ear are often increased. Other groups may be enlarged, but less often. Under unfavorable conditions, an enlarged lymph node may become inflamed, and the child will be bothered by pain, swelling, redness, or an increase in body temperature - in this case, an urgent need to consult a doctor. It is also worth sounding the alarm when lymph nodes increase to 1.0-2.0 cm., Periodic complaints of fever, frequent acute respiratory infections, which result in bacterial inflammatory processes. There are many life-threatening diseases that also cause an increase in lymph nodes, so combining any lymph node enlargement into one is not entirely correct, everything needs an individual approach, especially in the children's body, where all processes are more intense due to immaturity. ”

Lymph nodes in children

Lymph node inflammation occurs more often in children than in adults.. They can become inflamed, for example, if a bacterial or viral infection has entered the children's body, and this happens quite often in childhood.

However, if you find an enlarged nodule in a baby on the neck or under the armpit, you should not immediately suspect a terrible diagnosis, remember thatchildren's immune system responds faster and more actively on any "enemy penetration" into the body.

Our forumwomanEngla tells:“When my son had a fever, the lymph node in his neck increased and he got sick, we went to our pediatrician. She examined us and referred us to a hematologist in Ohmad. Before that, we passed free tests. Then the hematologist prescribed a paid one, and based on the results he diagnosed inactive lymphodenitis. Treated with antibiotics. Then the lymph node diminished, but small compaction sometimes develops, especially during illness. ”

Besides,The child’s immune and lymphatic systems are not yet fully formed.Thus, the volume of lymphoid tissue in relation to the volume of a child’s body is larger than that of an adult; therefore, in some children, the cervical and breech lymph nodes may remain enlarged for quite a long time.

However, this does not mean that you should not pay attention to the increase in lymph nodes.Medical consultation is requiredif the parents noticed that the baby's lymph node became more than 2 cm in diameter, the baby felt pain when palpating, and the skin around her turned red. Do not warm the inflamed lymph node and do not massage it before receiving a doctor.

Atlymphadenitischildren have a high fever, an enlarged lymph node rises and hurts, and appetite and sleep are disturbed. Typically, lymphadenitis in children occurs when a child has become ill with influenza, measles, rubella, infectious mononucleosis, viral pneumonia, caries, or viral hepatitis. In order to make a diagnosis, the doctor may prescribe you to pass urine and blood tests, to recommend examination by narrow specialists.
