What everyday habits are worth checking?
For constipation, the NHS recommends increasing fibre gradually, drinking fluids, allowing unhurried toilet time and responding to the urge to go. Raising your feet on a low stool and being more active may also help. Follow any individual advice you have received about fluid intake or activity.
These are starting points. If diet and lifestyle changes are not helping, a pharmacist can advise. Do not stop a prescribed medicine without speaking to your GP or prescriber.
Does bloating tell me which supplement to choose?
No. The NHS lists several possible causes of bloating, including gas, swallowed air, constipation, food intolerance and IBS. The symptom alone cannot establish which cause applies.
For live-culture products, the NHS explains that evidence for one type or use cannot automatically be applied to other products or problems. If you have an existing health condition or a weakened immune system, speak to a doctor before trying these supplements.
Where can I compare ARK products?
The ARK Supplement Quiz offers a way to browse products. Check the current ingredient list, directions and warnings on the product you are considering. The quiz does not establish what is causing a symptom, and this guide does not recommend an ARK product to treat a digestive condition.
When should I seek medical advice?
See a GP for recurring or persistent bloating or constipation, blood in your stool, unexplained weight loss or a sudden change in bowel habits.
Seek urgent medical advice for bloating with vomiting, diarrhoea, constipation, tummy pain, fever, a lump, or inability to pass urine, stool or wind. Call 999 or go to an emergency department for a swollen, bloated abdomen with sudden severe pain, vomiting blood or severe breathing difficulty.
These examples summarise the NHS bloating guidance and NHS constipation guidance; they are not an exhaustive list.
