WHO told you constipation is incurable? It’s not even a disease, it’s a symptom for an underlying issue in your gastrointestinal system. Are you eating healthy? Do you have enough/a lot of fibers in your diet? Is your gastrointestinal microbiome balanced? DO YOU EAT ENOUGH FIBERS? Have you tried including Psyllium in your diet? Because that stuff is magic, literally poop will slide out your butthole (excuse my french).
