Inflammatory bowel disease and bone health

Patient information A-Z

Children and young people lay down new bone until they are in their early twenties. If you have inflammatory bowel disease you are at risk of poor bone development during childhood and osteoporosis as an adult (thin bones that are more likely to fracture) due to:

  • Poor absorption of nutrition
  • Poor appetite and poor nutritional intake
  • Certain medications

It is important to make sure that you look after your bones so that they can grow and achieve their full potential.

Calcium

Calcium is the main nutrient in the development of strong healthy bones. The best source of calcium in the UK diet is dairy products such as milk, cheese and yogurt and fortified plant based products. You should aim to eat three to four portions of these per day. A portion is 200ml milk, 30g cheese or 100g yogurt.

Calcium is also found in smaller quantities in a variety of other foods, for example green leafy vegetables and pulses.

Calcium requirements are calculated as an amount per day and change according to age and gender.

Daily Calcium Requirements Amount of calcium recommended per day
Daily Calcium Requirements 0-12 months Amount of calcium recommended per day 525mg
Daily Calcium Requirements 1–3 years Amount of calcium recommended per day 350mg
Daily Calcium Requirements 4-6 years Amount of calcium recommended per day 450mg
Daily Calcium Requirements 7-10 years Amount of calcium recommended per day 550mg
Daily Calcium Requirements 11-18 years female Amount of calcium recommended per day 800mg
Daily Calcium Requirements 11–18 years male Amount of calcium recommended per day 1000mg
Daily Calcium Requirements 19 + years with IBD Amount of calcium recommended per day 700mg

Individuals on a cow’s milk or lactose free diet are at higher risk of calcium deficiency.

The following tables list good sources of dietary calcium (dairy and non-dairy) and the amount of calcium a typical portion contains. Please note this information is correct at time of publication but sometimes ingredients and nutrition change. Food labels can contain more information.

Other factors that affect your bones

Vitamin D

Vitamin D is made in your body following exposure to the sun. If you use a lot of sunscreen this process can be reduced, therefore it is important to get good sources from your diet. The main sources of vitamin D are dairy products, oily fish and butter/margarine. All children over the age of one should be taking a daily supplement containing 10 micrograms of Vitamin D, especially during autumn and winter.

Exercise

Weight bearing exercise can help build bones. This can be exercise such as running, football, rugby, hockey, athletics, trampolining and many more.

Steroids

Steroids used to treat inflammatory bowel disease can thin your bones if used for a long time. To minimise these affects you can also be given a calcium supplement while you are taking them. Calcium is best absorbed overnight, so supplements are best taken in the afternoon and before going to bed.

If you have any other questions about bone health ask your doctor or nurse to refer you to a dietitian for more advice. Additional information sheets are available for those following a dairy free diet upon request.
