Learn Everything about Diabetes Mellitus Symptoms

diabetes mellitus symptoms

Diabetes mellitus can sound like a scary disease to have. Most of us have grown up with the conception that diabetes is hard to treat and control. However, diabetes mellitus, if diagnosed early, can be treated and held in check. For this, it is important to watch out for the early signs of it. However, Diabetes Mellitus symptoms vary depending on the type of diabetes you have. In this article, we will cover everything that you need to know.

What is Diabetes Mellitus?

Diabetes Mellitus is a condition characterized by high blood sugar levels. The pancreas, a gland behind the stomach, is responsible for producing the hormone insulin, and the shortage of insulin is the underlying cause of high blood sugar levels. Shortage of insulin happens as the pancreas starts to wear out as we get older, which might accelerate the condition.

Sometimes, due to some underlying issues, the body is not able to fully utilize the insulin, which leads to the body overproducing the hormone before finally getting tired and being unable to keep up.

Diabetes Mellitus affects insulin production and glucose metabolism. They are mostly divided into three kinds:

  1. Type 1 Diabetes Mellitus (T1DM)
  2. Type 2 Diabetes Mellitus (T2DM)
  3. Gestational Diabetes

Type 1 Diabetes Mellitus

Type 1 diabetes is juvenile-onset or insulin-dependent. This arises from immune system injury to the pancreatic insulin-producing cells (beta cells). It primarily affects young people, whose pancreases produce so little insulin that they require insulin injections.

Type1 diabetes symptoms

  • Dehydration
  • Increased appetite
  • Mouth dryness
  • Excessive and repeated urination
  • Loss of body weight
  • Fatigue and deficiency of energy
  • Impaired vision
  • Tingling in the hands or feet
  • Sores take a long time to heal
  • Dry, itching skin
  • Repeated yeast infections on the skin, urinary tract, or vaginal area
  • Crankiness
  • Frequently wetting the bed as a youngster

Type 2 Diabetes Mellitus

The term “mature-onset diabetes” refers to diabetes mellitus that does not require insulin to control blood sugar levels. It mostly happens to people over 40, and many of those people are overweight or eat too many calories. This happens when the pancreatic cells generate glucose, but it is not enough, or when the cells have developed insulin resistance. Usually, a diabetic-conscious diet is enough to control it. Although in some cases, diabetes medication may be required. In addition, genetics, stress, or lifestyle changes can also develop this condition.

Type 2 diabetes symptoms

Gestational Diabetes:

Some women get this type of diabetes during pregnancy, which disappears once the baby is born. This is because the female body’s cells become more resistant to glucose during pregnancy because of hormone changes. However, these women are more likely to develop type 2 diabetes as they age.

Pregnancy (Gestational Diabetes) Symptoms:

  • Enhanced thirst
  • More frequent urination
  • Nausea/vomiting
  • Loss of weight even with a greater appetite
  • Impaired vision
  • Yeast infections

Diabetes warning Symptoms:

Diabetes can lead to the following common signs and symptoms:

  • Fatigue: Diabetes causes fatigue because there isn’t enough glucose to fuel the cells without insulin. The patient tends to experience weariness due to inadequate glucose uptake by the cells.
  • Hunger: Despite consuming large quantities of food, it is possible that diabetic patients would feel hungry more often due to the body’s inability to recognize the nutrients due to a lack of sugar processing.
  • Frequent urination: The inability of the renal system to reabsorb a significant amount of water during the digestion process causes water to be excreted as urine.
  • Thirst: Due to frequent urination, the body of a person with diabetes suffers from dehydration, which causes the patient to be constantly thirsty.
  • Dry mouth: Diabetes Mellitus symptoms include bad breath and dry mouth. This is due to a deficiency in the digestive system’s ability to absorb water.
  • Dry skin: Diabetes-related dehydration can cause flaky, itchy skin despite topical ointments.
  • Blurred vision: Diabetes’ long-term consequences include blurred eyesight and glaucoma.
  • Slow to heal cuts: Wounds tend to heal more slowly than normal in people with diabetes because the body cannot effectively aid in healing.
  • Weight loss: It’s possible to lose weight without sugar since the body can’t properly absorb the nutrients it gets from regular meals. This causes harmful weight loss in juvenile diabetics.

Diabetes-Related Complications:

Excess abdominal fat and lack of exercise seem to cause insulin resistance. Though modern diabetes treatment is highly effective, patients’ compliance with the treatment, particularly the diet, is critical to the success of the treatment. Untreated diabetes causes coma, renal failure, blindness, and heart problems. The feet and eyes are especially vulnerable and need extreme precautions and regular checks.


Diabetes is caused due to excess sugar levels in the bloodstream. The condition is caused due to lower or no insulin levels or the body’s inability to absorb insulin properly. Diabetic patients can control the situation by changing their lifestyle and eating habits. Leading an active lifestyle and consuming sugar and starch-free food can also help in controlling diabetes to some extent. However, it is always advisable to consult a doctor before starting any diet or medicine.
