Are Pregnancy Stretch Marks Hereditary

Are Pregnancy Stretch Marks Hereditary?

Stretch marks can appear when our skin expands more rapidly than its natural elasticity allows. This phenomenon is common during pregnancy, but it can also occur due to rapid weight gain or loss. Stretch marks can be unsightly and difficult to remove, which leaves us wondering: are stretch marks hereditary?

The Scientific Evidence

Medical experts have looked into this question over the years and the consensus is that genetics do play a role in the likelihood of developing stretch marks. While the exact cause for stretch marks is still unknown, researchers have identified certain risk factors, such as:

  • A family history of stretch marks
  • A decrease in collagen production
  • Hormonal fluctuations during puberty, pregnancy, or menopause

  • A rapid increase in weight or body mass index (BMI)

For pregnant women, family history is a key factor. If your mother had stretch marks during her pregnancy, there is an increased likelihood that you will, too. Research also suggests that women who are over the age of 25 are more likely to develop stretch marks during pregnancy than those who are younger than 20.

Treating Stretch Marks During Pregnancy

Though many women struggle with the physical and emotional effects of stretch marks during pregnancy, the good news is there are options for treating these skin changes. A few of the most common solutions include moisturizing products, laser and light treatments, and prescription creams.

Moisturizing products: Daily use of a moisturizing lotion or creme can help your skin retain elasticity and reduce the appearance of stretch marks.

No matter which course of action you take, it’s important to remember that prevention is key. Drinking plenty of water, getting adequate rest and nutrition, and maintaining a healthy weight will all help keep your skin elastic and healthy during pregnancy.


Stretch marks are a common concern for pregnant women, but understanding your risks and taking steps to keep your skin healthy can help reduce their appearance. While genetics can play a role in the likelihood of developing stretch marks during pregnancy, there are also other factors to consider, such as nutrition and lifestyle choices. If you’re concerned about stretch marks, talk with your doctor about the best prevention plan for you.
