Weakened immune system
Your immune system is a complex network of cells, tissues, and organs that work together to defend against germs. It protects your body against foreign invaders that can make you sick.1 The experience of grief can impact the immune system for e.g. event often accompanied by grief after the loss of someone close has numerous consequences for physical and mental health leading to a weakened immune system.2
A weakened immune system may also lead to illness and infections.2

Heart problems
Acute psychological stress is associated with an abrupt increase in the risk of cardiovascular events. A study observed that a person’s risk of having a heart attack was 21 times more likely in the first 24 hours after the death of a significant other. After 1 week, the risk was still almost 6 times as likely. The impact may be greatest among individuals at high cardiovascular risk.3
Stressful life events, such as death of a loved one or divorce, may also lead to a medical condition referred to as Broken Heart Syndrome. This is a short-term heart condition in which the heart does not pump normally and can occur in healthy people also. Symptoms include sudden, intense chest pain and shortness of breath. The pain is often so severe that it may be mistaken for a heart attack. Broken Heart Syndrome can cause short-term heart muscle failure, but is usually treatable.4

Alcohol and substance abuse
Parental loss has an overall impact on the functional impairment in the youth. A study that included 235 sons and daughters who had lost a parent showed that they had about a 2.4 times higher risk for alcohol and substance abuse compared to sons and daughters who had not lost a parent.5

Depression
There is an increased risk for adverse psychiatric events, namely, depression and posttraumatic stress disorder (PTSD), after the loss of a parent, sibling, or close friend.5
A study found that about 1 in every 4 widows and widowers experience clinical depression during the first year after their spouse’s death.6

Poor sleep
Many studies showed that people dealing with grief had trouble falling asleep and staying asleep. This was the case whether the individual was depressed or not. Sleep disturbance is common in individuals experiencing grief and may lead to poor physical and mental health outcomes.7
