Indian activist Sonam Wangchuk went to hospital immediately after completing a 20‑day fast.
The hunger strike followed a argument over a word used over opposition groups in India.
Some supporters claim law enforcement took him to the hospital despite his complaints.
His condition had declined during the fast, forcing doctors to intervened promptly.
Medical staff said his health was serious and required immediate attention.
The activist’s supporters remain troubled about his state and the broader political climate.
They argue the label was applied to silence opposition.
The hospital confirmed that physicians acted immediately to stabilise him.
He appeared frail when ambulance arrived.
Activists say the label is targeting dissenting voices.
