What are the common causes of sudden infant death?

Weakness, malnutrition, sudden illness, breathing problems, or accidents can all lead to death.

It may be caused by hyperthermia, abnormal brain development, congenital diseases, environmental factors, and human factors.

It is likely that the fetus is in poor physical condition, it may be due to asphyxia, it may be due to a congenital disease, and it may be because of the abnormal development of the baby's brain.

Several of these factors have been studied, including brain defects, immune system abnormalities, metabolic disorders, underdeveloped respiratory regulation mechanisms, or heartbeat disorders.

1.Environmental factors.

1) Pregnancy-related factors.

Many of the factors that increase the risk of SIDS are obstetric and suggest that the intrauterine environment is not optimal in patients who will develop SIDS. Children with SIDS are usually multiparous, have minor mothers, and have a short interval between their last pregnancy.

2) The environment in which the baby sleeps.

Studies have consistently demonstrated that prone sleep increases the risk of SIDS.

3) Smoking exposure.

Parental smoking is the most important risk factor for SIDS.

2.Brain defects.

There is growing evidence that some infants who die from SIDS have abnormal or immature brainstem development, and that it is this part of the brain that controls breathing and waking up during sleep. Normally, babies are able to sense problems such as lack of oxygen and too much carbon dioxide, but when the brain is not developing properly, they may lack this protective mechanism.

3.Immune system deficiencies.

Studies have shown that some babies who die from sudden infant death syndrome have higher than normal levels of white blood cells and protein produced by their immune systems. Some of these proteins interact with the brain, alter the rate of heartbeat and breathing during sleep, or put babies into deep sleep.

4.Metabolic disorders.

Babies with congenital metabolic disorders are more likely to die from SIDS. For example, if they lack a specific enzyme (medium-chain dehydrogenase), they may not be able to process fatty acids properly, and the accumulation of these acids will eventually lead to a rapid and fatal collapse of the breath and heart.
