#SWEETESTCAUSE is an online fundraising campaign that together with the Sugar Soirée is a chance for CHI's supporters to impact everything we do - every genetic test we fund, every research grant we fund, every conference we offer, every family we reach, and every patient we support.CHI is a lifeline to those born with congenital hyperinsulinism (HI) and their families, a rare disease that causes dangerously low blood sugar that can lead to brain damage and death. CHI is the only US patient organization dedicated to supporting children and adults born with HI all over the world. CHI funds and conducts research for better treatments and a cure. CHI is the foremost advocate for increased awareness and better medical protocols for HI to reduce preventable brain damage and death from prolonged low blood sugar.
