Identifying key triggers
Symptoms recap
Irritable Bowel Syndrome (IBS) is a gastrointestinal disorder that has a wide and varying range of symptoms including:
- Abdominal pain and discomfort
- Bloating
- Changes in your bowel habit – constipation or diarrhoea
Other related symptoms include wind, fatigue, nausea and lower back ache. You are able to track all of these symptoms in the Abdominal Health Diary in order to keep an accurate record of your abdominal health history.
There are a variety of lifestyle factors that can trigger IBS symptoms and, as everyone is different, these vary from person to person. However, the most common IBS triggers are listed below, some of which may or may not apply to you. You can track each factor on the Abdominal Health Diary.
Common triggers
Food (and drink) for thought
Breakfast benefits
Eating breakfast may be something that is easy to forget when things get busy, but it is important to eat breakfast to stimulate what is called the 'gastro-colic' reflex. Having a full stomach stimulates your bowel to move. If you delay this until later in the day, any solids sitting in your bowel stay there longer with more water being absorbed, increasing the chance of constipation.
Eating habits
IBS symptoms tend to be increased following large meals, especially if eaten quickly. It can sometimes be helpful to spread the food over three meals and three snacks per day. Avoid eating quickly and try to relax after a meal.
Wonderful water
It is important that you don't become dehydrated, so you may want to increase your fluid intake. Completing the Abdominal Health Diary will help you monitor how much fluid you are drinking each day. Remember, this doesn't include cups of coffee or alcohol!
Exercise - getting it right
Exercise can range from the gentle to the extreme. Whilst it is important to incorporate regular exercise into your lifestyle some exercises may not suit you and could actually be triggering IBS symptoms. Find out what works for you. Exercise that can be particularly helpful in improving digestive health includes aerobics, Tai Chi, swimming, yoga and pilates.
Stress busting
Stressful times in your life such as moving house or specific events like a job interview can trigger or worsen IBS symptoms. Some stressful situations can be controlled but it is those that can't be avoided that are often more troublesome. Keeping track of particularly stressful times can be useful to identify whether they are causing your symptoms and may mean that you can actively avoid certain situations in the future. If unavoidable, incorporating exercise or relaxation techniques into your daily routine may help relieve symptoms. When completing the diary it is important to consider that the impact of stress can sometimes be delayed and happen after the event, rather than on the actual day.
Key considerations
Whilst the factors listed above are simple to track and may directly correspond to symptom flair-ups, there are some key considerations to take into account which may explain why it is harder to pinpoint your triggers:
- Lack of sleep and disruption to your routine (whether going on holiday or at the weekends), can often lead to bowel problems. This may be why your symptoms increase or decrease on particular days regardless of your diet and other lifestyle factors
- Women on and before their periods may notice a flair-up of symptoms. This is natural, and also affects women not suffering from IBS
- It may be harder to notice whether a food is upsetting you if you are consuming it on a daily basis. For example, drinking orange juice or eating bran flakes every day. To sort this out it may be worth leaving the potentially offending food completely out of your diet for a while to see if your symptoms improve
- Unfortunately for some severe IBS sufferers, the physical action of eating can stimulate symptoms regardless of the specific foods you are eating. In this situation symptoms usually start very shortly after eating
- There are normally one or two food items that just don’t agree with people, such as onions. However, it is important to remember that this can be completely normal and there may be no underlying problem
- You may notice that some treatments such as anti-inflammatory painkillers or antibiotics upset your IBS. It is worth paying attention to any problems as alternative options may be available to you. Speak to your pharmacist or GP for advice
