Understanding Nexplanon: The Highly Effective Birth Control Implant

Nexplanon, a popular long-term birth control method, is more than 99% effective at preventing pregnancy. But how does it work, and what are its potential side effects?

How Nexplanon Works

Nexplanon is a tiny plastic rod placed under the skin on the inside of your upper arm. It releases a continuous low dose of etonogestrel, a progestin hormone that helps prevent pregnancy by thickening cervical mucus, thinning the uterine lining, and stopping egg release from the ovaries.

The Benefits of Nexplanon

This “set it and forget it” birth control method is convenient and effective, with no need to remember daily pills. It’s also more effective than hormonal birth control pills, which are 93% effective with typical use.

Weight Gain and Nexplanon

While Nexplanon is generally safe and effective, some people may experience side effects, including weight gain. Studies suggest that weight gain is relatively rare, with most people gaining only a small amount. For example, one study found that users gained an average of 7.9 pounds over two years, while a control group gained 6.8 pounds.

Factors That Influence Weight Gain

Research suggests that genetics, body weight, and certain health conditions can affect your susceptibility to weight gain when using Nexplanon. For instance, people with variations in the estrogen receptor 1 (ESR1) gene or a higher body mass index (BMI) may be more likely to gain weight.

Losing Weight While on Nexplanon

To maintain a healthy weight, focus on a balanced diet, regular exercise, stress management, and adequate sleep. If you’re experiencing weight gain and think Nexplanon may be the cause, consult your doctor to discuss options and rule out other possible causes.

Removing Nexplanon and Weight Loss

If you’ve gained weight due to Nexplanon, removing the implant should help you lose the excess weight. However, remember that healthy weight loss takes time and patience.

Other Potential Side Effects

In addition to weight gain, Nexplanon may cause:

• Changes in periods, headaches, vaginitis, breast pain, viral infections, stomach pain, mood changes, back pain, nausea, dizziness, and pain at the insertion site
• Rare complications include pregnancy due to improper insertion, ovarian cysts, increased risk of breast cancer, serious blood clots, liver tumors, high blood pressure, and gallbladder issues

Talk to Your Doctor

If you’re concerned about potential side effects or have questions about Nexplanon, consult your doctor. They can help you decide which birth control method is best for you.
