Step 3: Symptoms of diabetes


People with type 1 diabetes usually have a number of the following symptoms:

  • Frequent urination
  • Excessive thirst
  • Unexplained weight loss
  • Extreme hunger
  • Sudden vision changes
  • Tingling or numbness in hands or feet
  • Feeling very tired much of the time
  • Very dry skin
  • Sores that are slow to heal
  • More infections than usual
  • Nausea, vomiting, and stomach pains


Not everyone will notice drastic symptoms -- the symptoms may be subtle or go unnoticed at first. In some cases, the first symptom is frequent yeast infections.


Type 1 diabetes occurs when a person's own immune system gradually attacks and destroys the cells in the pancreas that produce insulin. As these cells are destroyed, insulin production drops, eventually stopping completely.

Therefore, people with type 1 diabetes must use insulin daily. If they miss their injections or take too much, the levels of glucose in the blood can fluctuate out of control, getting very high or very low and leading to emergency medical situations.

This possibility is not something that should make you live in constant fear. When you learn to monitor and control blood glucose level, which includes careful meal and snack planning, you will become a confident expert at keeping yourself (or your child) healthy.
