Effects of Depression on the Body

Depression is a common psychological state. In certain circumstances, it is even normal, such as after the loss of a loved one or a traumatic experience. Other times, it may be caused by a physiological chemical imbalance. Whatever the cause, depression affects the body in various ways.

  1. Appetite

    • Depending on the individual, depression may cause weight loss or weight gain. Depressed individuals may eat more because they find comfort or relief in eating, or the body may naturally suppress biological functions such as appetite.

    Immune System

    • The immune system is affected by depression because stress hormones are released into the body. When stress hormones are released over long periods of time, the immune system can become suppressed.

    Physical Pain

    • Because the uptake of serotonin, a chemical produced in the brain that assists with pain tolerance, can be inhibited in depressed individuals, depression can cause physical aches and pain.

    Sleep

    • Depressed individuals may see an increase in the amount of time spent sleeping or experience difficulty falling asleep. Depression affects REM cycles, which in turn can cause unnatural sleep behaviors or disturbances.

    Fatigue

    • Depression can cause the individual to feel tired, worn out or unable to accomplish even small tasks. Depression-induced Insomnia can contribute to feelings of fatigue.
