A doença de Lyme é fatal?

Lyme disease is the infection caused by bacteria. The bacterium evades the immune system by unknown mechanism and begins to invade the vital organs of the body. The condition becomes more severe when the test fails to positively diagnose the patient. Bacteria mainly attack the nervous system and the heart system and lead to fatal consequences. Thus, the approach is to diagnose the disease as early as possible and then treat it with appropriate therapy.

Is Lyme disease fatal?

Whether or not Lyme disease is fatal depends on the time elapsed for diagnosis, initiation of treatment and effectiveness of treatment. The effectiveness of treatment also includes adherence to treatment. When proper diagnosis of the disease is not made, or proper treatment is not provided, Lyme disease can move to the second stage, where the vital organs of the body, such as the brain and heart, are severely affected and when these organs are severely affected. damaged. To the extent that they can no longer function effectively, the result can be fatal. Lyme disease, in its severe form, affects the brain and heart. Brain-related symptoms may include  neuropathy  ,  visual disturbances  , paralysis of the face, and meningitis, such as symptoms such as fever, stiff neck. and severe headache. Other symptoms may include irritability, cognitive dysfunction, and peripheral nerve damage. It also affects the nerves that control breathing and can lead to respiratory failure. In the heart, it is capable of causing Lyme carditis. About 7-8% of infected people are estimated to develop heart-related complications. Bacteria bypass the immune system and, when untreated, can enter the heart cells and interfere with proper conduction of electrical impulses. This can lead to cardiac arrhythmia. The other complication includes palpitations,  shortness of breathand passing out. When these conditions persist for a long time, it can be fatal as it can lead to complete heart block. In one study, Lyme disease was found to be a rare cause of death in the United States, but the risk increases with late diagnosis and treatment.

Lyme Disease Complications

In many cases of Lyme disease, the patient is asymptomatic for a few days with only a rash at the bite site. Thus, there is a delay in starting treatment, which increases the severity of the infection. In addition, if the patient has symptoms that are not specific to Lyme disease, it may be due to various other diseases. This may end up consuming more time. What adds to this complexity is the lack of availability of the highly sensitive diagnostic method for Lyme disease. Tests available in the current scenario carry the risk of providing false negative results. This may be due to low antibody sensitivity, antibody unavailability, immunosuppression and seronegative patients.

  1. Chronic joint  inflammation : There will be joint inflammation and the joints are swollen. There is also tendonitis and pain.
  2. Neurological disorders such  as neuropathy, facial paralysis, visual disturbances and symptoms of meningitis.
  3. Cognitive Defects
  4. Carditis:  Includes  chest pain  , palpitations, and ECG changes   .


The proposition of fatality of Lyme disease depends on the proper diagnosis and the time required for the diagnosis of the disease. Due to unsophisticated diagnostic methods, testing can yield false negative results. These delays cause the disease to enter the second stage, which is difficult to treat. Bacteria evade the immune system and move to the organs, some of which are vital. If bacteria attack the nervous system, respiratory depression can occur leading to death. In addition, bacteria also attack the heart and can cause palpitations, fainting, and shortness of breath. This can also lead to complete heart block leading to fatal consequences.
