Dynamo, 35, took to Twitter this week to raise awareness for a condition he has suffered since he was a teenager – Chrohn’s disease.
Crohn’s disease is a long-term condition that causes inflammation of the lining of the digestive system.
Dynamo posted a video where he said medication for the condition has caused his recent change in appearance.
He said in the video: “I’ve been keeping a bit more of a low profile as I got really sick and ended up in hospital last summer due to a really bad type of food poisoning – which having Crohn’s disease and food poisoning is a very bad combination.”
So what are the symptoms of the condition, worth looking out for?
The inflammation caused by Crohn’s disease can affect any part of the digestive system, from the mouth to the back passage, but most commonly occurs in the last section of the small intestine or the large intestine.
Dr Zoe on This Morning said vague symptoms can involve not feeling well, feeling feverish or ill all the time.
Others may be joint pain and swelling, inflammation and irritation of the eyes, areas of painful, red and swollen skin, and mouth ulcers.
More common symptoms can include diarrhoea, abdominal pain, fatigue and blood and mucus in your faeces.
Dr Zoe said in light of Dynamo’s video. she hopes people will be able to speak out about their Crohn’s experiences a little more.
The NHS says the exact cause of Crohn’s disease is unknown, but research has suggested a cow combination of factors may be responsible .
Genetics – genes you inherit from your parents may increase your risk of developing Crohn’s disease.
The immune system – the inflammation may be caused by a problem with the immune system (the body’s defence against infection and illness) that causes it to attack healthy bacteria in the gut
Previous infection – a previous infection may trigger an abnormal response from the immune system
Smoking – smokers with Crohn’s disease usually have more severe symptoms than non-smokers
Environmental factors – Crohn’s disease is most common in westernised countries such as the UK, and least common in poorer parts of the world such as Africa, which suggests the environment has a part to play (known as the hygiene hypothesis)
Treatment for Crohn’s disease
Where possible, surgery is avoided, and the first treatment offered to reduce symptoms is usually stored medication.
In some cases, surgery may be needed to remove the inflamed section of intestine.
If this happens, usually a stoma – an artificial opening made by a surgeon to bring part of the intestinal tract out through the abdominal wall – will be given to the patient.
A bag is attached to the stoma opening to collect the waste material and this will need emptying regularly.
