Hello, I went through your query, good her Thyroid hormones are in well control. Please continue her medicines. For all individuals growth spurt starts once they enter adolescent age growth, Eating good nutrition food continaining, proteins like meat, pulses or protein powder helps her gain weight. Jogging, skipping, playing tennis, swimming makes her more fit and gain weight and height.
