Symptoms of Diabetes

Symptoms of Diabetes: Introduction

Symptoms of diabetes can be vague or very dramatic, depending on the individual and the type of diabetes. Both type 1 diabetes and type 2 diabetes can present with excessive thirst, excessive urination, fatigue, weakness, weight loss, and blurred vision.

Type 2 diabetes generally develops from prediabetes gradually over a long period of time, often in older adults, and symptoms may not occur or be noticeable for years. In contrast, type 1 diabetes develops quickly, often in children, and symptoms can be striking. If not treated promptly type 1 diabetes can quickly result in critical conditions, such as diabetic ketoacidosis, hyperosmolar hyperglycemic nonketotic syndrome, shock, and death.

Left untreated, all three types of diabetes can lead to serious long-term complications, such as kidney failure, blindness, serious skin infections, gangrene, diabetic neuropathy, peripheral vascular disease, cardiovascular disease, birth defects, and stroke.

Pregnant women who develop gestational diabetes often do not have symptoms. They may however, experience excessive thirst and excessive urination. Complications of untreated gestational diabetes include the development of preeclampsia in the mother and developmental problems, respiratory distress syndrome, and excessive growth of the baby....more about Diabetes »

Diabetes symptoms: The symptoms of diabetes progress according to the range and duration of high blood sugar levels. The symptoms usually start mild (e.g. poorly healing skin rashes), and then progress to the more severe symptoms (e.g. excessive thirst and urination), and then finally to the dangerous life-threatening conditions of HHNS or DKA. The progression of symptoms is usually slow over years for Type 2 diabetes and rapid over weeks or months for Type 1 diabetes. People with Type 2 diabetes often are undiagnosed long enough that they start to get symptoms of the complications of diabetes, such as kidney and foot problems....more about Diabetes »

Article Excerpts About Symptoms of Diabetes:

Am I at Risk for Type 2 Diabetes: NIDDK (Excerpt)

Many people have no signs or symptoms. Symptoms can also be so mild that you might not even notice them. Five million people in the United States have type 2 diabetes and do not know it. Here is what to look for:

  • increased thirst
  • increased hunger
  • fatigue
  • increased urination, especially at night
  • weight loss
  • blurred vision
  • sores that do not heal

Sometimes people have symptoms but do not suspect diabetes. They delay scheduling a checkup because they do not feel sick. Many people do not find out they have the disease until they have diabetes complications, such as blurry vision or heart trouble. It is important to find out early if you have diabetes because treatment can prevent damage to the body from diabetes. (Source: excerpt from Am I at Risk for Type 2 Diabetes: NIDDK)

Keep your kidneys healthy: NIDDK (Excerpt)

An early sign of kidney damage is when your kidneys leak small amounts of a protein called albumin (al-BYOO-min) into the urine.

With more damage, the kidneys leak more and more protein. This problem is called proteinuria (PRO-tee-NOOR-ee-uh). More and more wastes build up in the blood. This damage gets worse until the kidneys fail. (Source: excerpt from Keep your kidneys healthy: NIDDK)

Some people with diabetes feel "run down" or have symptoms that may go unrecognized. Others have symptoms such as feeling thirsty, urinating frequently, losing weight, feeling tired, having blurred vision, getting skin infections, and having slow healing cuts and bruises. These problems should be reported to a doctor right away. (Source: excerpt from Dealing With Diabetes -- Age Page -- Health Information: NIA)
