Depression is a major risk factor for many serious diseases and disorders, including substance addiction, suicide, diabetes, and heart disease.

Some sufferers of depression experience very severe symptoms and seek help.

But others have milder symptoms that are not related to depression. For example, those suffering from the so-called "smiling depression" can have a social life and adequately fulfill their professional or other obligations, even though they suffer internally.

In addition to the classic symptoms of depression, such as low mood and the inability to derive pleasure from any situation, there are other symptoms that should motivate you.

Changes in sleeping habits

If you used to sleep well and now have restlessness, or 6 hours of sleep was enough for you and now you want to sleep all weekend, you need to get it checked out. Changes in sleep patterns can be a sign of depression. You may also experience what experts call "psychomotor agitation," which causes restlessness and an inability to rest.

Your mind is confused

Cognitive function is something you should pay attention to. Some people cannot sit for 30 minutes and watch TV, read or do anything that requires concentration. Other subtle signs of depression can include slow thinking, lethargy, and an inability to make decisions.

Rumination of negative thoughts

Rumination is the tendency to revisit the same issues over and over again. He usually focuses on negative situations and becomes obsessed with specific issues that he cannot overcome and get out of his mind. Rumination has been linked to anxiety, depression, PTSD and even bulimia. This results in the person entering a vicious circle of negative thoughts. When a person thinks depressing thoughts, those thoughts make them feel depressed and moody, which in turn creates new negative or stressful thoughts. This leads to feelings of despair, frustration and disappointment.

Changes in weight

Changes in weight can be a warning sign of depression. Some people start eating too much and some people stop eating. These changes can be accompanied by fatigue and lack of satisfaction. Depression affects chemical processes in the brain related to pleasure and appetite control.

Inability to express emotions

People who were previously sociable and devoted to family, friends, work, etc., but gradually withdraw from many activities, may be at risk of depression. Lack of sociability and isolation are characteristics of depression, as is the inability to express emotions.

Physical pain

Depression can cause many unexplained physical problems, such as headaches, digestive problems, and back pain. Although the pain is intense, often the diagnosis does not lead to depression. Pain and depression share the same brain chemicals, which "travel" along specific neural pathways. The result is that depression changes the brain's sensitivity to pain.

Depression and heart disease can also go hand in hand. Research has shown that those with depression and heart disease are at greater risk of death. Depression, like hypertension and high cholesterol, is a serious risk factor for heart disease, reports Ora News.
