The 29-year-old was pooing up to 40 times a day and at his lowest point he “felt like dying”.
Unable to control his bowel movements, Seb even had to defecate in the public hospital sink.
His condition was worsened due to the stress of his son Hayden, now seven months, and he suffered extreme diarrhoea for 24 hours.
At one point he was fighting wife Emily Bridges, 32, for the bathroom – and even had to use a sink in Worthing Hospital.
He said: “Hayden was due on 31 December last year but didn’t arrive until 13 January this year.
“Despite the stress and anxiety this caused I was okay until we got to Worthing Hospital for Emily to give birth.
“It was 2am and tiredness can affect my condition.
“It was a difficult labour and due to the stress I went to the toilet around 20 times in the next 24 hours.
“I was worried I was going to miss the birth.
“On one occasion I couldn’t use the bathroom because she was in it. She’d heard having a bath could relieve the pain of labour.
“I made it to the sink just in time.”
Seb wanted to be there for wife Emily, but had to keep dashing off to the toilet every few minutes.
“Another time Emily was having a contraction when I needed the toilet, and so she was holding my hand,” he said. “It meant I couldn’t move and I had to hold on.
“The contraction lasted about a minute. I had to dash off as soon as it had finished,” he added.
“When it came to Emily giving birth though, I was ok. Somehow I got to see Hayden come in to the world.”
Seb, who runs a web design agency, was diagnosed with the illness in 2008 after spotting blood down the toilet.
He said: “I was initially going to the toilet around 20 times a day.
“But within a few days it became closer to 40 times a day. I lost 10 kilos.
“I felt like dying. It was such a relief to get diagnosed, I broke down in tears.”
He was put on steroids for three to four years to bring the inflammation down and get his condition under control.
But after they left him feeling lethargic, he decided to see if there was anything else he could do to manage his condition.
He researched his condition online and decided to alter his diet. He tried cutting out dairy products, gluten, processed food and alcohol.
He ate meat and fish, fruit and vegetables, and rice, which he found were easy to digest and supported his immune system, which helped his ulcerative colitis.
“I learnt some food was rough, like sandpaper, and went straight through me so I changed my diet and suddenly felt healthier than I had in years,” he said.
Now Seb and Emily are trying to help other who suffer with Crohn’s Disease and ulcerative colitis.
They have just six days left to raise the remaining £13,000 they need to help them pay for a website they launched in May, called ibdrelief.com.
So far around 2,000 people have signed up to it.
Seb, who is asking for donations via crowdfunder.co.uk, said: “A lot of people struggle with inflammatory bowel diseases, like Crohn’s and ulcerative colitis, but they’re scared of talking about it.
“We set up the websie to teach others some of what I’ve learnt about how to cope with the condition and manage it, as there’s no real sharing out there.
“I would have loved to have spoken to someone like me when I was first diagnosed.
“Anyone who makes a pledge now will receive a reward, one of these being a ‘Get Caught Short’ kit, which includes wet wipes, tissues, antibacterial liquid and spare underwear.”
The NHS said: “Ulcerative colitis is a long-term condition, where the colon and rectum become inflamed.
“The colon is the large intestine (bowel), and the rectum is the end of the bowel where stools are stored.
“Small ulcers can develop on the colon’s lining, and can bleed and produce pus.
“The main symptoms of ulcerative colitis are: recurring diarrhoea which may contain blood, mucus or pus, abdominal pain and needing to empty your bowels frequently.
“Ulcerative colitis is thought to be an autoimmune condition. This means the immune system – the body’s defence against infection – goes wrong and attacks healthy tissue.
“It is estimated that around 1 in every 420 people living in the UK has ulcerative colitis; this amounts to around 146,000 people.
“The condition can develop at any age, but is most often diagnosed between 15 and 25.”
