Mitochondrial disease is an inherited, chronic illness that can be present at birth or develop later in life. “Mito” is progressive and can cause physical, developmental, and cognitive disabilities. Symptoms can be mild, such as tiredness or weakness, or they can be severe, such as poor growth, loss of muscle coordination, muscle weakness and pain, seizures, vision and/or hearing loss, gastrointestinal issues, learning disabilities, and organ failure. Approximately 1 in 4,000 people have Mito. There is no cure, but there are treatments that can help with the symptoms.
