Pregnancy and IBS: What Every Mum-to-Be in the UK Should Know

Irritable Bowel Syndrome (IBS) is a common condition that affects the digestive system. It often causes stomach pain, bloating, gas, and changes in bowel habits like diarrhoea or constipation. Many women experience IBS during pregnancy or may already have it before becoming pregnant. During pregnancy, hormone changes, stress, and pressure on the stomach can sometimes make IBS symptoms worse. It’s important for pregnant women with IBS to understand how pregnancy might affect their condition. This helps them manage symptoms better and stay comfortable. Eating a healthy diet, staying hydrated, managing stress, and getting regular checkups can support both digestive health and a healthy pregnancy. How Pregnancy Affects IBS Symptoms: Causes and Changes During pregnancy, a woman’s body goes through many changes, especially in hormone levels. These changes can affect different parts of the body, including the digestive system. Some women notice that their symptoms of Irritable Bowel Syndrome (IBS) improve during pregnancy, while others may find that their symptoms get worse. Some women may notice their symptoms get worse, while others might find them improving. 🔺 Why can symptoms get worse? 🔻 Why can symptoms get better? As the baby grows, it puts pressure on the intestines. This can slow down digestion and cause discomfort. If you have IBS during pregnancy, you might face issues like increased gas, stomach pain or cramps, constipation, or sometimes diarrhoea. These symptoms can sometimes feel like normal pregnancy discomforts, which makes it hard to tell the difference. That’s why it’s important to monitor any changes and talk to your doctor if you notice anything unusual. How to Safely Manage IBS During Pregnancy? Managing IBS (Irritable Bowel Syndrome) during pregnancy needs extra care. It’s important to work closely with your doctor or a qualified dietitian. They can help you follow a plan that keeps both you and your baby safe. Experts like 121 Dietitian specialise in digestive health and give special advice for pregnant women.

She has helped many patients recover using her unique and science-based programs. At 121 Dietitian, we believe in offering patients the latest medical and research-backed treatments. We are proud to provide this special care to our clients. One key program we offer is the Low FODMAP Diet for IBS (Irritable Bowel Syndrome). This diet has been successful for over 75% of people worldwide, while the official UK guidelines show about 30% success. But at 121 Dietitian, our success rate is even higher—95%. This is because we treat the whole person, not just the symptoms. Our detailed and personal approach sets us apart, especially in Northern Ireland. Gillian Killiner was the first dietitian in London trained in Low FODMAP Diet in 2011. Since then, she has been a source of hope for people with IBS, whether in Northern Ireland, the UK, or other countries. Why choose our Gut Health program? Many patients come to us after trying many tests and treatments with no success. Some have avoided certain foods for years but still have gut problems. When foods are removed incorrectly, the body can lack important nutrients like protein, vitamins, and minerals. This can cause tiredness, weakness, sadness, and other health issues. Also, some medicines for acid reflux or stomach pain can reduce nutrient levels over time, making problems worse. That is why we created different Gut Health programs in Belfast to solve these common but serious issues. Every person gets a customised plan. This may include the Low FODMAP Diet to reduce symptoms and improve health. This helps reduce symptoms like bloating or stomach pain, without causing any lack of nutrition.
