But if you have any of the following symptoms of depression for more than 2 weeks, call your doctor: Feeling restless or moody Feeling sad, hopeless, and overwhelmed Crying a lot Having no energy or motivation Eating too little or too much Sleeping too little or too much Having trouble focusing or making decisions Having memory problems Feeling worthless and guilty Losing interest or pleasure in activities you used to enjoy Withdrawing from friends and family Having headaches, aches and pains, or stomach problems that don't go away Your doctor can figure out if your symptoms are caused by depression or something else. What causes depression? What about postpartum depression? There is no single cause. Rather, depression likely results from a combination of factors: Depression is a mental illness that tends to run in families. Women with a family history of depression are more likely to have depression. Changes in brain chemistry or structure are believed to play a big role in depression. Stressful life events, such as death of a loved one, caring for an aging family member, abuse, and poverty, can trigger depression. Hormonal factors unique to women may contribute to depression in some women. We know that hormones directly affect the brain chemistry that controls emotions and mood. We also know that women are at greater risk of depression at certain times in their lives, such as puberty, during and after pregnancy, and during perimenopause. Some women also have depressive symptoms right before their period. Depression after childbirth is called postpartum depression. Hormonal changes may trigger symptoms of postpartum depression. When you are pregnant, levels of the female hormones estrogen (ESS-truh-jen) and progesterone (proh-JESS-tur-ohn) increase greatly. In the first 24 hours after childbirth, hormone levels quickly return to normal. Researchers think the big change in hormone levels may lead to depression. This is much like the way smaller hormone changes can affect a woman's moods before she gets her period. Levels of thyroid hormones may also drop after giving birth. The thyroid is a small gland in the neck that helps regulate how your body uses and stores energy from food. Low levels of thyroid hormones can cause symptoms of depression. A simple blood test can tell if this condition is causing your symptoms. If so, your doctor can prescribe thyroid medicine. Other factors may play a role in postpartum depression. You may feel: Tired after delivery Tired from a lack of sleep or broken sleep Overwhelmed with a new baby Doubts about your ability to be a good mother Stress from changes in work and home routines An unrealistic need to be a perfect mom Loss of who you were before having the baby Less attractive A lack of free time Are some women more at risk for depression during and after pregnancy? Certain factors may increase your risk of depression during and after pregnancy: A personal history of depression or another mental illness A family history of depression or another mental illness A lack of support from family and friends Anxiety or negative feelings about the pregnancy Problems with a previous pregnancy or birth Marriage or money problems Stressful life events Young age Substance abuse Women who are depressed during pregnancy have a greater risk of depression after giving birth. What is the difference between "baby blues," postpartum depression, and postpartum psychosis? Many women have the baby blues in the days after childbirth. If you have the baby blues, you may: Have mood swings Feel sad, anxious, or overwhelmed Have crying spells Lose your appetite Have trouble sleeping The baby blues most often go away within a few days or a week. The symptoms are not severe and do not need treatment. The symptoms of postpartum depression last longer and are more severe. Postpartum depression can begin anytime within the first year after childbirth. If you have postpartum depression, you may have any of the symptoms of depression listed above. Symptoms may also include: Thoughts of hurting the baby Thoughts of hurting yourself Not having any interest in the baby Postpartum depression needs to be treated by a doctor. Postpartum psychosis (seye-KOH-suhss) is rare. It occurs in about 1 to 4 out of every 1,000 births. It usually begins in the first 2 weeks after childbirth. Women who have bipolar disorder or another mental health problem called schizoaffective (SKIT-soh-uh-FEK-tiv) disorder have a higher risk for postpartum psychosis. Symptoms may include: Seeing things that aren't there Feeling confused Having rapid mood swings Trying to hurt yourself or your baby What should I do if I have symptoms of depression during or after pregnancy?
