Many people in Kampala and across Uganda first learn they have diabetes by accident. Someone goes in for a fever or a stubborn wound, a nurse checks their sugar, and the number comes back high. By then, the condition may have been present for years.
Diabetes can build up quietly, and most people who have it feel fairly well in the early days. That is exactly why it helps to know the signs and to get tested early. Medical experts at UMC Victoria Hospital highly recommend regular blood sugar tests for early detection and care of diabetes.
What Are the Early Warning Signs of Diabetes?
Early warning signs of diabetes often develop slowly and can easily be overlooked or mistaken for everyday tiredness. Recognizing these subtle indicators early is crucial for getting tested and managing blood sugar levels before complications arise.
-
Unexplained fatigue
Feeling constantly tired or sluggish, even after getting a full night's sleep. -
Increased thirst (Polydipsia)
Feeling unusually thirsty and unable to settle a dry mouth with normal water intake. -
Frequent urination (Polyuria)
Visiting the toilet more often than usual, especially waking up multiple times during the night. -
Increased hunger (Polyphagia)
Feeling excessively hungry shortly after eating a full meal. -
Unintentional weight loss
Losing weight without making changes to your diet or exercise routine. -
Blurry vision
Sudden or gradual trouble focusing clearly due to fluid shifts in the lens of the eye. -
Tingling or numbness
A pins-and-needles sensation, numbness, or burning, particularly in the feet or hands. -
Slow-healing cuts or sores
Small wounds, scratches, or bruises taking weeks to heal, or frequent skin infections. -
Dark skin patches (Acanthosis Nigricans)
Dark, velvety patches of skin appearing around the neck, armpits, or groin.
What Are the Common Symptoms of High Blood Sugar?
When sugar stays high in the blood, the body tries to flush it out through urine. This explains the classic symptoms:
-
Frequent urination
Especially at night, and sometimes in large amounts. -
Constant thirst
A dry mouth that water does not fully settle. -
Extreme tiredness
Because the body cannot use sugar for energy properly. -
Blurred vision
High sugar can swell the lens of the eye. -
Slow-healing wounds or repeated infections
Including skin boils, urinary infections, and thrush. -
Numbness or burning in the hands and feet
A sign that nerves may be affected.
If you feel very unwell, with vomiting, stomach pain, fast breathing, or unusual drowsiness, go to the nearest hospital immediately. These can be signs of a dangerous complication.
When Should You Get Your Blood Sugar Checked?
Do not wait for symptoms. A few situations call for a test:
- You have any of the warning signs described above.
- You are 35 or older and have never been tested.
- You are younger but overweight, particularly if you carry weight around the waist.
- You are planning a pregnancy, or you are pregnant.
- You have recently had an infection that is not clearing, or a wound that will not heal.
If your result is normal, repeat the test every one to three years, depending on your risk. If it is borderline, your doctor may ask you to come back sooner.
Who Should Get Tested for Diabetes?
Some people carry a higher risk and should be tested regularly, even when they feel perfectly well. This includes:
- People with a parent, brother, or sister who has diabetes
- Those with high blood pressure or high cholesterol
- Women who had gestational diabetes in a past pregnancy, or who delivered a very large baby
- Women with PCOD or PCOS
- People who are overweight or who sit for most of the day, such as office workers, taxi drivers, and shopkeepers
- Anyone with a history of heart disease or stroke
Our daily diet matters too. Meals built mostly around posho, rice, white bread, and sugary tea or soda, with little movement during the day, raise the risk over time. This does not mean giving up the foods we love. It means eating them in sensible portions and getting checked.
What Tests Are Used to Diagnose Diabetes?
Diagnosis is simpler than most people expect. Your doctor may use one or more of these tests:
-
Fasting blood sugar
Measured after at least eight hours without food. Water is fine. -
Random blood sugar
Taken at any time of day, useful when symptoms are present. -
HbA1c
A blood test that shows your average sugar level over the past two to three months. No fasting is needed. -
Oral glucose tolerance test
You drink a sugary solution, and your blood is checked after two hours. It is also used to screen for diabetes in pregnancy.
A finger-prick test at a pharmacy can give a quick idea, but a laboratory test is needed to confirm the diagnosis. If the result is high, the doctor will usually repeat it to be sure.
What Blood Sugar Levels May Indicate Diabetes?
Numbers can feel confusing, so here is a simple guide. These are the commonly used values, and your doctor will interpret them in your own situation:
-
Fasting blood sugar
Below about 5.6 mmol/L is generally normal. A reading of 7.0 mmol/L or higher on two occasions suggests diabetes. -
Random blood sugar
A reading of 11.1 mmol/L or above, together with symptoms, points towards diabetes. -
HbA1c
Below 5.7% is considered normal, and 6.5% or above suggests diabetes.
Readings between normal and diabetic are called prediabetes. Please do not ignore this result. It is a warning that the body is struggling with sugar, and at this stage lifestyle changes can often bring numbers back to normal.
Why Is Early Diabetes Detection Important?
Sugar that stays high for years slowly damages small and large blood vessels. Over time this can affect the eyes, kidneys, nerves, heart, and feet. We see patients who come to us with failing eyesight, kidney problems, or a foot ulcer that began as a small blister, and many of them did not know they had diabetes until the complication appeared.
When diabetes is found early, the story is different. Many people manage well with changes in food, regular walking, and, when needed, tablets or insulin. Treatment is also usually simpler and less costly when started early than when it is delayed until complications develop. Families benefit as well, because one person's diagnosis often prompts relatives to get tested too.
When Should You See a Doctor About Diabetes Symptoms?
Consult a diabetes doctor in Uganda if you notice increased thirst, frequent urination, unexplained weight loss, or unusual tiredness lasting more than two weeks. Do not wait if you have blurred vision, tingling feet, or a wound that is not healing.
Pregnant women should discuss testing at their first antenatal visit. And if you already know you have diabetes but your sugar keeps running high despite treatment, come back for a review. Medicines and doses often need adjusting over the years.
Seek emergency care straight away if you are vomiting, confused, breathing rapidly, or extremely drowsy
