Can you tell me the calcium resorption?
Get a blood test and try to check your insulin as it can have a massive effect on your muscles.
When you are awake, you should always have breakfast, eat protein (chicken, meat, fish, eggs, milk) which will help your muscles a lot so that you no longer lose your bones.
I suggest you visit, also write on the foot. Dr. Solomon Jakobuchs is an endocrinologist, who was confirmed, he wrote a letter to him that he denied it! And it can really help you identify the cause of sudden weight loss.
