While thyroid issues don't directly cause smelly urine, they can increase the risk of conditions that do, like diabetes (sweet smell) or urinary tract infections (UTIs, ammonia/foul smell). Both underactive (hypothyroidism) and overactive (hyperthyroidism) thyroids are linked to changes in the urinary system, potentially leading to issues like UTIs or bladder problems, making smelly urine a potential indirect symptom.
There's no direct link between an underactive thyroid and sweet-smelling urine. Be aware, however, that autoimmune Hashimoto's thyroiditis and hypothyroidism are associated with a significantly increased risk of type 1 and type 2 diabetes and a mixed autoimmune form called Latent Autoimmune Diabetes in Adults (LADA).
However, it has been shown that hypothyroidism can lead to changes in the urinary system, leading to: Decreased glomerular filtration rate (GFR), leading to kidney failure and reduced clearance of waste products from the blood. Water retention, leading to edema. Electrolyte imbalances, including hyponatremia.
Some conditions that can cause changes in urine odor include:
Common signs
For thyroid health, the "one thing" to focus on daily is a source of iodine, found in dairy, eggs, or seafood, and selenium, best from a few Brazil nuts, both crucial for hormone production, but a balanced breakfast with protein, fiber, and healthy fats, like eggs with spinach or oatmeal with berries, provides comprehensive support, while avoiding excessive iodine or simple sugars is key.
What Are the Symptoms of Thyroid Disease?
In lupus nephritis, your glomeruli are damaged by inflammation, allowing proteins into your urine. In addition to smelling like chicken broth, your urine may be foamy or frothy. Other symptoms of lupus nephritis include edema (swollen legs, face, and hands), blood in your urine, and weight gain.
You should worry about urine smell and see a doctor if it's persistent, accompanied by fever, pain/burning during urination, cloudy or bloody urine, or if it smells sweet (potential diabetes) or rotten (potential infection/kidney stones). While often temporary due to dehydration or food, persistent strong or unusual odors, especially with other symptoms, warrant medical attention to rule out UTIs, diabetes, or other conditions.
Key takeaways:
Foul-smelling urine is not a symptom of cancer. The most common cause of foul-smelling urine is a urinary tract infection.
Contact your healthcare provider as soon as possible if you notice these common symptoms of hypothyroidism:
One of the most accurate and effective ways to assess thyroid function is through a 24-hour urine test. This method offers several advantages over blood tests: Provides a comprehensive view of hormone levels over a full day rather than a single point in time.
Hashimoto's disease is an autoimmune disorder. The immune system creates antibodies that attack thyroid cells as if they were bacteria, viruses or some other foreign body. The immune system wrongly enlists disease-fighting agents that damage cells and lead to cell death.
While thyroid disorders don't directly cause sour-smelling sweat at night, a change in thyroid hormone production can impact the rate of sweating. In turn, more sweat can result in body odor.
Both hypothyroidism and hyperthyroidism can cause sleep issues. In patients with hyperthyroidism, the nervousness and arousal associated with the condition can prevent patients from falling asleep normally. Increased perspiration caused by the condition can lead to night sweats, waking the patient during the night.
Thyroid Preventive Care Package
Excessive consumption of these foods can result in thyroid gland inflammation and worsen the condition. These include: Some fruits, such as strawberry, peaches, Starchy food, such as sweet potato and cassava.
Bladder infection. Cystitis (irritation of the bladder) Dehydration — when the body doesn't have enough water and other fluids to work as it should. Diabetic ketoacidosis (in which the body has high levels of blood acids called ketones)
Things you can do if you have smelly pee
There are a number of common causes for smelly urine. Certain foods. Different strongly-scented foods, such as brussels sprouts, asparagus, onions, and garlic, can make strong-smelling or foul-smelling urine. These types of foods are converted into sulfur compounds which can smell like rotten cabbage or eggs.
Patients affected by trimethylaminuria will often have fishy-smelling urine. Trimethylaminuria is a genetic disorder in which affected individuals have an enzymatic deficiency that makes them unable to metabolize TMA. Because they cannot metabolize TMA, affected individuals have a buildup of TMA in their bodies.
If your kidneys aren't working properly, you may notice one or more of the following signs:
Kidney failure can make urine smell strongly of ammonia or have a fishy odor, often due to built-up waste products (amines) or infection, signaling concentrated urine from dehydration or kidney dysfunction. Other signs alongside bad-smelling urine include foamy, bloody, or cola-colored urine, swelling, fatigue, and changes in urination, all pointing to potential kidney issues that require a doctor's evaluation.
Thyroid problems (hypo- or hyperthyroidism) show up as changes in energy, weight, mood, and body temperature, with common signs including fatigue, unexplained weight changes, anxiety/depression, feeling too hot or cold, hair loss, skin/nail issues, heart rate changes, and neck swelling (goiter), affecting metabolism and overall bodily function. Symptoms vary but often manifest as a slowed-down body (hypothyroidism) or an over-sped-up one (hyperthyroidism).
Daily habits such as irregular sleep, skipped meals, and stress can harm thyroid function. Improving your routine can offer significant relief and support hormonal recovery.
