Dwamena was diagnosed with a ventricular arrhythmia in 2017. In January 2020, while at Levante UD he had an implantable cardioverter-defibrillator (ICD) implanted through surgery, which enabled his club to monitor his heart during matches. In October 2020, the ICD showed values which were considered too high, and his club at the time, Vejle Boldklub, withdrew him from team activities as a result.
In October 2021, in Austrian Cup match during the first half of Blau-Weiss Linz's game against Hartberg, Dwamena collapsed on pitch, was shocked by the ICD and stabilized quickly.
