Why Might There Be Blood in My Urine?
Finding blood in your urine, known as hematuria, is a causefor concern and warrants immediate medical attention. Possible reasons include:
· Urinary Tract Infections(UTIs)
· Kidney Infections (Pyelonephritis)
· Enlarged Prostate (BenignProstatic Hyperplasia - BPH)
· Bladder Cancer or Kidney Cancer
· Injury to the Urinary Tract
· Certain Medications (e.g.,blood thinners, aspirin)
· Vigorous Exercise
· Inherited Disorders (e.g.,Alport syndrome)
· Glomerulonephritis (inflammation of kidneyfiltering units)
What Causes Urine Colour Changes?
1. Dehydration
2. Food and Drinks (Beets, Berries, Food dyes)
3. Medications (Certain antibiotics e.g., rifampin, Laxatives, Chemotherapy drugs)
4. Vitamins and Supplements (Vitamin B and Vitamin C)
5. Liver Diseases (Hepatitis, Cirrhosis)
7. Urinary Tract Infections
8. Kidney Disorders (Glomerulonephritis)
9. Muscle Damage (Rhabdomyolysis)
10. Porphyria (rare genetic disorder)
11. Metabolic Conditions (Hypercalcaemia)
How Can the Smell of Urine Indicate Health Problems?
Dehydration. When the body lacks adequate water, urine becomes more concentrated, producing a stronger smell. The urineis darker yellow or amber urine with a strong, pungent odour.
Urinary Tract Infections (UTIs). Bacterialinfections in the urinary tract can cause urine to develop a foul or ammonia-like smell.
Certain Foods and Drinks. Classical examples include Asparagus (distinctive sulphur-like smell), coffee and certainspices.
Medications and Supplements can cause a change in urine smell. Antibiotics like penicillin and Vitamin B6 supplements arecommonly the culprits.
Diabetes and Diabetic Ketoacidosis. High blood sugar levels can cause urine to havea sweet or fruity smell, indicative of diabetes. Diabetic ketoacidosis, aserious complication, can also cause a strong, fruity odour. Symptoms include excessive thirst, frequent urination, fatigue, and confusion (in severe cases).
Liver Disease can cause urine to have a musty smell due to the buildup of toxins. Typical symptoms include jaundice(yellowing of the skin and eyes), dark urine, and fatigue.
Metabolic and genetic disorders can lead to unusual urine smells. Rare examples include Maple syrup urine disease(urine smells like maple syrup), Phenylketonuria (PKU) (musty odour), Trimethylaminuria(fish odour syndrome), and Isovaleric acidemia (sweaty feet smell).
Bladder Fistula is an abnormal connection between the bladder and the intestines can cause urine to have afoul smell due to the presence of faecal matter. Symptoms include recurrenturinary tract infections, presence of gas in urine.
How Does High Blood Sugar Appear in Urine?
Hyperglycemia can result in excess glucose in the urine, although this isn’t visible to the naked eye. This condition, known as glycosuria, occurs when blood sugar levels exceed the kidney's ability to reabsorb glucose, causing it to spill into the urine. Glycosuria is a common sign of diabetes.
What Are Ketones and Why Do They Appear in Urine?
Ketones are chemicals produced by the liver when the body starts breaking down fat for energy due to a lack of available sugar (glucose). This process usually occurs during periods of fasting, prolonged exercise, or when carbohydrate intake is very low. In people with diabetes, high levels of ketones in the urine often indicate a serious condition called diabetic ketoacidosis (DKA).
DKA happens when insulin levels are too low, and the body cannot use glucose for energy, leading to the breakdown of fat and the accumulation of ketones. Symptoms of DKA include:
- Fruity-smelling breath
- Frequent urination
- Extreme thirst
- Nausea or vomiting
- Abdominal pain
- Confusion
DKA requires urgent medical attention as it can be life-threatening. Early detection and treatment are essential to manage blood sugar levels and prevent the development of DKA. Regular monitoring of blood glucose and ketone levels is important for individuals with diabetes to detect and address potential issues promptly.
How Can Urine Tests Detect Pregnancy?
Home pregnancy tests work by identifying the presence of the hormone human chorionic gonadotropin (hCG) in urine. This hormone is produced by the placenta shortly after a fertilised egg attaches to the uterine lining, typically around six days after fertilisation. The levels of hCG increase rapidly in the early stages of pregnancy.
For the most accurate results, it is recommended to perform the test 5 to 10 days after a missed period. This timing allows for hCG levels to be sufficiently high to be detected by the test.
What Does Foamy Urine Indicate?
Foamy urine can indicate excess protein in the urine, a condition known as proteinuria,which is often due to diabetic kidney disease. This condition arises when high blood sugar levels damage the kidneys’ filtering system, allowing proteins like albumin to leak into the urine and create a foamy appearance. Other causes of foamy urine can include dehydration, rapid urination, or reactions with cleaning chemicals in toilets. Diagnosing proteinuria involves urine tests to measure albumin levels and blood tests to assess kidney function. Early detection and management of underlying conditions, such as diabetes and hypertension, are crucial to preventing the progression of kidney disease andpotential kidney failure. If you notice persistent foamy urine, it is importantto consult a healthcare provider for appropriate evaluation and treatment.
What Do Dark Urine and Jaundice Indicate About Liver Health?
Dark urine and jaundice (yellowing of the skin and eyes) are significant indicators of potential liver or gallbladder issues. These symptoms often arise due to an increase in bilirubin, a yellow pigment that is a byproduct of red blood cell breakdown. When the liver is unable to process bilirubin properly, it accumulates in the blood, leading to jaundice and darkening of the urine. Here are some common causes:
- Drug Overuse: Excessive use of medications such as acetaminophen can lead to liver damage, impairing its ability to process bilirubin.
- Cancer or Gallstones: These can obstruct bile ducts, preventing bilirubin from being excreted and causing it to build up in the blood.
- Hepatitis C: This viral infection causes liver inflammation and damage, disrupting normal bilirubin processing.
These conditions highlight the importance of liver health in regulating bilirubin levels and preventing its accumulation. If you notice dark urine and jaundice, it's crucial to seek medical attention for proper diagnosis and treatment.
How Does Vasculitis Affect Urine?
Vasculitis, the inflammation of blood vessels, can significantly impact urine characteristics, often leading to tea-coloured urine. This discolouration occurs because the inflammation can cause blood and protein to leak into the urine. Additionally, vasculitis can manifest with symptoms such as fever and body aches.
If vasculitis affects the kidneys, it can lead to glomerulonephritis, where antibodies mistakenly attack the kidney's filtering units. This can cause damage and impair the kidneys' ability to filter waste properly. If left untreated, this condition can progress to kidney failure, a serious and potentially life-threatening complication.
Prompt diagnosis and treatment are essential to manage vasculitis effectively and protect kidney function. If you experience symptoms such as tea-coloured urine, fever, and body aches, it's important to consult a healthcare provider for appropriate evaluation and management.

Any change in the colour of your urine should raise red flags to seek medical help.
