sudden weight gain, ringing in the ears, difficulty sleeping
feeling hungry all of the time, increased thirst, waking up at night to urinate
Number 4 is correct.
Rationale: Signs of Type 1 diabetes include polyphagia (increased hunger), polydipsia (increased thirst), and polyuria (increased urine output). While some of the answers in responses 1, 2, and 3 are correct, they are not all indicative of the specific signs of type 1 diabetes. Swollen lymph nodes, muscle weakness, bloating, ringing in the ears, and difficulty sleeping are associated with other medical diagnoses.
