Which are the symptoms of Diabetes?
Symptoms of Diabetes reported by real patients, from the most common to the most limiting, plus a medically reviewed summary with sources.
The primary symptoms of Diabetes include excessive thirst (polydipsia), frequent urination (polyuria), unexplained weight loss, and persistent fatigue resulting from the body's inability to effectively process glucose.
Common Symptoms and Early Warning Signs
In the early stages of Diabetes, the body struggles to move sugar from the bloodstream into cells. Patients often report blurred vision, slow-healing sores or frequent infections, and a significant increase in hunger, even after eating. Because these symptoms can develop gradually, they are sometimes dismissed as minor fatigue or stress, making it vital to monitor persistent physiological changes.
Symptom Severity and Daily Impact
The severity of Diabetes symptoms varies greatly between individuals depending on their glycemic control and the specific type of the disease. For many, the most significant impact on quality of life involves the constant need for glucose monitoring and the disruption of sleep caused by nocturia (frequent nighttime urination). Chronic fatigue often limits physical activity, while nerve pain (neuropathy) can significantly hinder mobility and comfort in daily tasks.
Progression and Seeking Care
Over time, if Diabetes remains unmanaged, symptoms may evolve to include numbness or tingling in the hands and feet due to nerve damage. It is critical to seek immediate medical attention if a patient experiences nausea, vomiting, abdominal pain, fruity-smelling breath, or confusion, as these can be signs of diabetic ketoacidosis—a life-threatening emergency. Early intervention is the most effective way to slow the progression of Diabetes-related complications and maintain long-term health.

When I go on a Diabetic low, It can be a minor one where I can still do the things that I need to while eating some sugar. They can also be major lows where I start to sweat, so much so, that I look sometimes like I have just taken a shower. I usually feel really terrible and tired. I can also start speaking gibberish to people and can struggle to even draw or cut out a triangle.(Real experience in my algebra math class in middle school.) This can be dangerous especially when I am doing things like trying to get sugar for a low and can't find my sugar, even when it is sitting right where I am looking! If I could get rid of the symptoms of a major diabetic low, I would.
When I go on a Diabetic high, It can also be a minor one where I give myself insulin and I don't really feel any big symptoms. If it is a major diabetic high, then I can feel sluggish or nauseated. I also feel extra thirsty and will (no joke) have to pee every 3-5 minutes. It can really limit me when this happens because when I am sluggish, I struggle with simple things at my job like teaching math concepts.

The symptoms that got me diagnosed were sudden weight loss, extreme thirst (my mom would have to cut me off because I would just keep asking for more water), and constantly going to the bathroom.
Now, my symptoms have to do with blood sugar. When it's high, I feel jittery, thirsty, always need to use the bathroom, have no appetite, and can't sleep. When I'm low, my body shakes and feels weak, I feel extremely hungry, I get brain fog, and I feel tired. If my blood sugar drops quickly, I feel nauseated.

It is my strong belief that this is the worst condition in all of humanity right now… I believe this for the main reason that this disease is never ending. It is a 24 seven disease, where in one must check blood glucose levels religiously. disease is also just dropped with the wash of cultural reference points… It's not just a food disease… Most people are simply concerned about carbs and sugars… For the conscious diabetic, all things including proteins and fats must be counted up… One takes 1/3 of the fat grams and 1/2 of the protein grams to add up the complete net carbs at every meal…
On top of this, many children do not come into the grips of finding the benefits of taking care of this adamant disease that is always at attention until they're much older… This leaves a Wishingwell… Denial… For most of the teenage years! Note: most children get this disease [are diagnosed with T1D] at the onset of puberty/ adolescence [This occurs just when the thymus reaches its quintessential peak of largess… From that time on the thymus gets smaller and smaller until it becomes most vestigial in adulthood. I am not aware of research. However, what I mean by this is that when I was diagnosed with T1G back in 1989, I had doctors and residents at my bedside who were interested in taking a peek at my history… At that time, case histories where the norm and,[Much like Oliver Saks would dictate years later before his death…"The case study is essential the advancement of modern medicine."
