Is It Normal To Feel Fatigued Several Weeks After Delivering The Baby?

Yes, the feeling of fatigue and exhaustion are common and may last weeks to even months after the child’s birth. The rate of fatigue increases from 20% in the antepartum period to 50-64% in the postpartum period (1).

How tired you are also depends on how well you adjust to the baby’s napping schedule and how much help you have at home.

What Are The Causes Of Postpartum Fatigue?

Several factors contribute to lethargy or fatigue several mothers experience during the postpartum period (2).

  1. Birthing process: It can take you hours and a lot of energy to push the baby out of the birthing canal. Recovering from a C-section, which is a major abdominal surgery, can also make you tired quickly.

It takes about six weeks to recover from a C-section. However, the time may differ from one person to another (11).
  1. Lack of sleep: Sleep at night is scarce with a newborn in the house, especially if you are the mom! You may try to nap when your baby is sleeping. But then, daytime is the only time for you to get things done, which means you will be sleep deprived and fatigued for most of the time. Sleeplessness due to stress and postpartum hormonal changes is another issue that can also contribute to postpartum fatigue.

  4. Hypothyroidism: Some women may develop an underactive thyroid gland in one to four months after delivery. Postpartum fatigue will be a symptom of this condition, which needs medical intervention, and a healthy diet and lifestyle (6).

Apart from these, first pregnancy, decreasing hormone levels, colic in the newborn, and poor diet and exercise can also contribute to postnatal fatigue. Since weariness is more of a symptom than a condition, it can only be managed but not treated.

How To Deal With Postpartum Fatigue?

These simple tips can help you cope with physical, mental, and emotional fatigue or enervation (7).

  4. Identify your newborn’s sleep patterns: Your baby will not follow the same routine of waking up several times a night. As they turn older, they will sleep for longer periods at night. Understand how much sleep they need, and what their timings are so that you can schedule your work accordingly.
  5. Exercise: Regular exercise will make you feel less tired. Walking every day with your baby lets you get some fresh air, and the movement helps you both sleep better. According to the US Centers for Disease Control and Prevention (CDC), moderate exercising for 150 minutes/week leads to happier moods, healthy heart and lungs, and improved energy levels.
  1. Try relaxation exercises: Practicing deep relaxation techniques for five to ten minutes every day can leave you refreshed. Start with simple relaxation exercises such as breathing and learn other techniques online or by reading books.
  2. Drink plenty of fluids: Staying hydrated gives you the energy you need in a day and also boosts your mood. According to the CDC, consuming sufficient water will regulate the body temperature, lubricate joints, protect the spinal cord, and remove wastes through perspiration, urination, and stools.
  3. Choose guests wisely: To avoid unnecessary strain that can trigger feelings of listlessness, it is perfectly fine to say no to visits or an extended stay of guests. Be choosy about who you want to spend time with, as being with the right people will make a difference. Bond with your little one instead of other people and see how rewarding it would be for you and your baby..
  4. Follow a perfect diet: Even if you do not have enough time for yourself, try to make healthy food choices to ward off postpartum fatigue. Include complex carbohydrates and proteins, and have the vitamin supplements prescribed by the doctor. Stop worrying about weight gain as this is not the right time to go on a crash diet. Nevertheless, skip sweets and caffeine.
