You might not have all of these. Doctors call it "major depression" if you have at least 5 of these symptoms for at least 2 weeks. People with major depression might also have other physical symptoms, such as pain or other illnesses that get worse, stomachaches, headaches, or digestive problems.
Depression can range from mild to severe. Doctors used to call the milder forms “dysthymia” if it lasted for at least 2 years in adults (1 year in children and teens). Now, it’s called "persistent depressive disorder."
Everyone feels sad or blue now and then. Those are normal emotions. Depression is different. If it lasts more than 2 weeks and doesn’t lift, or if you start to notice other physical symptoms such as changes in sleep, appetite, or energy, seek help. You could start with your regular doctor or a mental health professional.
Call Your Doctor If:
You or a loved one has suicidal thoughts.
You think you or a loved one is depressed. There are effective treatments.
It’s also wise to check in with your doctor if you are considering alternative or complementary treatments for depression. Your doctor can help you weigh the risks, benefits, and what’s best for you.
