Can Depression Be Life-Threatening?

Though many people with depression lead fulfilling lives and often find treatment plans that work for them, it's important to be aware of the fatalities that do occur in those who have suffered from this mental health condition.

One of the main ways that depression might lead to death is if the negative symptoms result in a person deciding to take their own life. Depression can make people feel helpless and without hope, causing them to reach the unfortunate conclusion that suicide is the only way to end their misery.

Increased Risk of Suicide

According to the Centers for Disease Control and Prevention (CDC), suicide was the 10th leading cause of death among all age groups in the year 2017. In 2016, there were nearly 45,000 deaths attributed to suicide in the United States.

The other half, about 54%, of people who died by suicide did not have a known mental health condition, according to the CDC.

What to Do

If you are experiencing symptoms of depression, talk to your doctor or mental health professional. They can recommend treatment options, such as antidepressants and talk therapy, both of which can relieve symptoms and help you feel better.

Self-Medicating

Depression can also lead some individuals to turn to drugs and or alcohol to self-medicate emotional problems. This can occur more often when people are unable to deal or cope with painful feelings of sadness, isolation, anger, hopelessness, and stress.

Dual diagnosis complicates the treatment of depression since both conditions must be dealt with as separate, yet interconnected, issues. 

The National Institute on Drug Abuse reports that one in four deaths in America can be blamed on alcohol, tobacco, and illegal drug use. In addition, the Substance Abuse and Mental Health Services Administration states that substance misuse is one of the biggest risk factors for suicide.

What to Do

If you have symptoms of depression and substance misuse, it is important to talk to your doctor about your feelings and behaviors. An appropriate diagnosis can help ensure that you get the right treatment to address each condition.

Short-term treatments involve quitting any substances you might be using. Your doctor can make recommendations about the detox and withdrawal process. Depending on the substance in question and the frequency and duration of use, your doctor may recommend inpatient residential treatment or outpatient options to assist during this process.

In some cases, you may be able to go through this process at home, but you should always talk to your doctor first. Drug withdrawal can be life-threatening in some cases and requires professional intervention and medical monitoring.

Long-term treatments of dual-diagnosis issues may involve the use of antidepressants, psychotherapy, and other medications to address symptoms of depression and include:

• Behavioral counseling
• Cognitive-behavioral therapy
• Contingency management
• Group therapy
• Medications to aid in recovery
• Support groups

Illnesses Linked to Depression

Chronic illness can also increase the risk of depression. In some cases, this may be because of the stress of coping with illness makes it more likely that a person will experience symptoms of depression. Some health conditions, such as stroke and Parkinson's disease, can also cause changes in the brain that contribute to depression.

According to the National Institute of Mental Health, depression can be common in people with illnesses including:

• Alzheimer's disease
• Cancer
• Diabetes
• Epilepsy
• Heart disease
• HIV/AIDS
• Multiple sclerosis
• Rheumatoid arthritis
• Stroke

Research suggests that depression can make co-existing illnesses harder to treat because if you're not feeling well emotionally, it's harder to comply with your treatment regimen.

In addition, people with depression appear to be at greater risk of contracting certain illnesses, such as heart disease. All of these factors combined may put people at greater risk for dying from their medical illness than they otherwise would be if they did not have depression.

Further research is still needed to explore the connection between depression and other medical conditions. Some suggested theories include the fact that it may be more difficult for people with depression to take care of their health and they may have less access to medical care.

Physiological changes such as increased inflammation and alterations in stress hormones may also play a role.

What to Do

Collaborative treatment options that address symptoms of depression, lifestyle, and other illnesses can be effective at managing co-existing depression and chronic conditions.

If you have a medical condition and are experiencing symptoms of depression, talk to your doctor. In some cases, such as if you have a thyroid condition, what you are feeling may actually be connected to your illness and treating the underlying condition may help relieve symptoms of depression.

Treatment options often involve the use of psychotherapy, medications, or a combination of both. One study found that both evidence-based psychotherapy and antidepressants were effective at treating symptoms of depression in individuals with co-occurring diabetes.

Complications of Depression

If you're depressed, it's harder to make good lifestyle choices. You may not sleep or eat well, you may not get much exercise, or you may drink, smoke, or use drugs. All of these factors can increase the risk of illness and poor health, which, in turn, makes a person more likely to die prematurely.

Potential complications of depression can include the following:

Diabetes

Research suggests that people with depression are much more likely to develop diabetes, although it is not clear if one causes the other or vice versa. One study found that people with major depression and diabetes with or without evidence of heart disease have a higher number of cardiovascular risk factors.

Nutritional Deficiencies

Some studies suggest that nutritional deficiencies may contribute to depression and that dietary changes that are a symptom of depression may also lead to deficiencies, including:

• Amino acids
• B vitamins
• Minerals
• Omega-3 fatty acids

Stress-Related Effects

Stress can contribute to symptoms of depression, and depression can lead to increased stress. Stress can have a wide variety of negative health effects including:

• Anxiety
• Decreased immunity
• Sleep disturbances

It can also trigger and aggravate other medical conditions.

Self-Help Strategies

Along with the individual treatment plan that you and your mental health professional develop to treat your depression, you can also employ some self-help strategies to help stave off feelings of sadness or emptiness.

Here are some ideas:

• Call a friend or close family member
• Dance to your favorite music
• Join a gym to get exercise, a natural mood booster, and make new friends
• Keep a journal
• Walk or cuddle with your pet
• Paint, color, or draw
• Use relaxation techniques, like guided imagery or yoga

A Word From Verywell

When you're depressed, it can seem like your life will never get better and nothing will ever help, but that's not the case. Depression is highly treatable with medication such as antidepressants, psychotherapy, or a combination of the two.

Talk to your doctor about your symptoms, but always reach out to emergency services immediately if you are in immediate danger.
