Possible Causes
Generally, Almost passing out can be related to:
- Multiple Myeloma (MM)
This is a cancer of a type of white blood cell in the blood, called a plasma cell. Cancerous cells multiply and "crowd out" other healthy, normal cells. Risk factors include positive family history, older age, and male sex. Symptoms include fatigue, bone pain, weight loss, and inability to fight infections.
- Hypertrophic Cardiomyopathy
Hypertrophic cardiomyopathy is a condition where the heart muscle becomes thick. It is often caused by gene mutations in the heart muscle. The thickened heart muscle can become stiff, reducing the heart's ability to pump blood adequately.
Depression
Depression is a mental illness that leads to low mood, reduced energy levels, and changes in sleep. This affects everyday activities like attending school and work. As the condition worsens, patients might have suicidal thoughts. Although stress and past trauma can cause depression, it can take time to identify and address causes, and genetic factors may also be at play.
- Adjustment Disorder
- Benign Arrhythmias (Palpitations)
- Migraine
- Peri-/Post-Menopausal Symptoms
Related serious diseases
Sometimes, Almost passing out may be related to these serious diseases:
- Epilepsy
Epilepsy is a neurological disorder where brain activity becomes abnormal, causing seizures of varying durations and severities. It can affect people of any age and may be caused by genetic disorders or brain injuries, such as stroke.
- Heatstroke
- Cerebral Infarction
