After a hernia and paraesophageal repair, you'll need to make some changes to your diet as you heal. This can help you get the nutrition you need. It may also help with nausea, which may make you not feel like eating. It's common for people who've had this surgery to lose weight in the first 4 to 6 weeks after the surgery.
As your body heals, you'll follow a mild diet. This can promote healing. It can also help reduce the risk of nausea, vomiting, and gagging. If you vomit or gag a lot, you risk delaying healing.
Your doctor may prescribe anti-nausea medicine for the first 24 to 48 hours after surgery so you can eat.
