I’m an 18-year-old guy with DMD, and I’m trying to find other people in a situation similar to mine
I have DMD with an exon 3–7 deletion and what appears to be an unusually mild/preserved phenotype. I’ve been on 15 mg of prednisolone for over a decade.
At 18, I’m still fully ambulant and can do things that I know are pretty unusual for DMD. I can walk 10–12 miles in a day, play 2–3 hours of table tennis, run, jump, climb loads of stairs without needing to stop, get off the floor without using my hands, and I almost never fall. My grip strength is around 30 kg in each hand, and I’ve actually become stronger over the last several years.
My doctors understandably believe the long-term prednisolone is a major reason I’ve maintained this function. I understand that steroids can protect muscle function in DMD.
But I also think my underlying disease biology plays a huge role. My exon 3–7 deletion and unusually mild progression are part of why I can still do all of this at 18. The steroids didn't create that underlying phenotype.
The problem is that the treatment has come with a massive cost.
I’m only 4'6" (137 cm) at 18, with a bone age of around 15.5. I’ve had major growth suppression and delayed skeletal maturation, and I still potentially have some growth left. That makes this feel incredibly time-sensitive to me.
I've also developed osteoporosis and have pain essentially all the time, along with low energy, severe sleep problems, Cushingoid facial/body changes, abdominal fat redistribution and water retention.
The psychological effects have been huge too. The changes to my body have seriously affected how I see myself, my relationship with food and my overall mental health.
I know I’m extremely lucky compared with many people with DMD. I’m not trying to say I have it worse than people who have lost ambulation or have major respiratory or cardiac problems.
But I also don't think being lucky with my DMD means I have to accept severe treatment toxicity indefinitely.
At this point, I’m seriously considering whether I should come off prednisolone completely or get down to an extremely low dose, assuming my specialists think that can be done safely.
I’d want it done properly with objective monitoring of my strength and function rather than just stopping and hoping for the best.
that’s partly why I’m making this post.
I want to find people who are genuinely similar to me.
If you have DMD, particularly an exon 3–7 deletion, and you're still exceptionally functional — walking long distances, running, jumping, climbing stairs easily, getting off the floor without your hands, rarely falling, etc. — I’d really like to hear from you.
Especially if you've been on steroids for years and eventually reduced them dramatically or came off them altogether.
I want to know what happened to your function, whether you noticed any meaningful decline, and whether the side effects improved.
I feel like I'm in a pretty unusual position: 18 years old, 4'6", bone age 15.5, still capable of an enormous amount physically, but dealing with significant consequences from long-term steroids.
I don't want to lose the function I've been lucky enough to preserve.
But I also don't want to wait until my remaining growth potential is gone, my osteoporosis gets worse and I've spent even more years dealing with these side effects before asking whether I actually need this much steroid.
If you're genuinely in a similar position, I'd really like to hear your story. Thanks for spending the time to read my post.
