I see so many people online talking about they wanting to become diaper dependent, and some others saying that they want to make other diaper dependents, that I decided to give my take on this. You can also go directly to the end of the piece: no, is not good for you, and I don't endorse it.
I don't endorse the practice of deliberately becoming diaper dependent, for many reasons. Becoming diaper dependent by making your bladder weaker and getting you to lose it's control is creating a condition for yourself that you did not had. Using a diaper (if you don't need it for medical reasons) for extended periods of time can weaken your bladder control and lead to atrophy of the muscles you need in order to pee. This is called "disuse atrophy" and can make it hard for you to regain control, or at least without medical intervention. I will never promote anything that will make the health of my clients worsen.
Think that in future you might want to regain control of your bladder, and that is not guaranteed this will happen. Losing autonomy over your body can have lasting psychological effects, especially when your dependency was intentionally induced rather than happening for other medical reasons.
Consider that urinary incontinence may affect your sex life too. Is this something you would actively choose? And to add to it, consider the financial cost. Diaper dependency is costly.
With medical grade nappies, let's calculate the cost. I checked some Tena online. A pack of 30 tena nappies cost around £16 to be sent home. If you use about three a day, (minimun) that is 1,095 nappies a year, 36.5 packs per year, and an annual cost of £584 (of course it will cost less if you get them prescribed). But if is not Tena, and you are using printed nappies, let's say a pack of Little Rascals contains 10 nappies and that is £27 transport included, wich will result on 2,956.50 a year (or a bit less if you buy the bigger package, but still a lot to consider).
I am aware that some poeple who have a medical reason to use nappies due to incontinence and sometimes chronic health conditions turn to the ABDL community in search for comfort, acceptance and friends, and I am glad that they can find them in such an embracing community. But inducing diaper dependency when it is not medically necessary is a very different thing. The wish to regress and enjoy ABDL activities can be fulfilled in many other health and non permanent ways that don't compromise your body functions, and I reccomend to use nappies with common sense and not excessively, so this can't happen.
There are also cases where people did not intend to become dependent on their nappies but their bladder muscles became week accidentally, from using the nappies a lot. If this could be your case or you find yourself getting close to this, it is important to consult with a doctor as soon as possible, so they can help you regain control.
I cann't give advice on how to do it, but I shall mention that the bladder can be trained. Mine has changed a lot since I stopped fulfilling the instruction my own mum would give me "have you peed?" before leaving the home, that would make me force myself to pee sometimes when I did not need it. Scheduling bathroom visits at intervals and increasing the time between visits can definitively help, as well as pelvic floor excersises.
I do understand that when someone has severe anxiety and finds that wearing nappies help them feel safe and secure, this will encourage using them more, and when this anxiety is severe it is important to consider their mental health needs, and ponder them against the long term effects of diaper dependency. So yes, there are special circumstances where I would understand someone making the decissions to use them all the time, regardless, if it helps to manage some overwhelming emotions, and when other methods have not worked. But I would still approach this solution with caution, becasue even if they can help as a coping mechanism, they can also mask the real issues or causes of the anxiety, and stop people from developing more strategies that would help them, but support is needed too here in any case, in the shape of a specialist a therapist or similar to help them address the causes of this anxiety.
Remember, if you are struggling with your bladder due to using your nappies (or diapers) a lot, seek professional help. You deserve the best care for your health and your well-being, and unless you need them for medical reasons (either physical or mental), my advice is use in moderation, enjoy, and keep your balance.
