I am a 25 year old female. I was diagnosed with a mitochondrial deficiency when I was 19 and told that I might not have known I had it if not for the high level of cardio I did during Irish Step. Mind you, I have always been overweight as active as I was. I am very muscular, but I also hold extra weight. Recently I have gotten much worse. My weight is climbing to the point that I needed to quit dancing and I have no ability to deal with heat and I become ill when I get hot. The heavier that I get the worse the symptoms are (dizziness, nausea, fatigue) yet it s hard to workout because of the symptoms. I have tried cutting back calories and carbs in different ways but nothing lasts because I feel too weak when I do. Really not sure what to do at this point.
