One possible plot could be that Harry was seriously injured in a dark magic attack. The feeding tube is a result of his inability to eat normally due to the damage to his body. He has to struggle not only with the physical pain but also with the stigma in the wizarding world where such a medical device might be seen as a sign of weakness. Meanwhile, his friends try to find a magical cure to get rid of the need for the feeding tube.
Perhaps Harry is cursed in a way that affects his digestive system. The fanfic could revolve around his journey to understand the curse and find a way to reverse it while living with the feeding tube. It could also show how his relationship with others changes. Some might pity him, while others see his determination to keep going in spite of the feeding tube as a sign of great strength. He might also discover some new magical abilities or knowledge in his search for a cure.
In a 'Harry Potter' fanfic where Harry has a feeding tube, the plot could start with Harry being poisoned by a new type of dark - magic - created toxin. The feeding tube is a temporary measure to keep him alive. As he recovers, he uses his time to study the toxin and find a way to not only cure himself but also prevent others from being affected. Along the way, he has to deal with the Ministry of Magic's interference as they are afraid of the implications of this new dark magic. His friends, Hermione and Ron, stand by him throughout the ordeal, and together they explore ancient magic texts and consult with wise wizards to find a solution.
