Swelling in your hands, feet, abdomen or face..

Why is my urine yellow and smelly?

If you’re dehydrated, you may notice that your urine is a dark yellow or orange color and smells like ammonia. Most people only experience minor dehydration and don’t require medical treatment. Drinking more fluids, especially water, will generally cause urine odor to return to normal.

What controls the concentration of urine?

Urine volume and concentration is regulated through the same processes that regulate blood volume. Antidiuretic hormone (ADH)—produced by the posterior pituitary gland —increases the amount of water reabsorbed in the distal convoluted tubule and collecting duct.

Why is urine yellow in Colour?

Normal urine color ranges from pale yellow to deep amber — the result of a pigment called urochrome and how diluted or concentrated the urine is. Pigments and other compounds in certain foods and medications can change your urine color. Beets, berries and fava beans are among the foods most likely to affect the color.

Is clear Urine Good?

Clear urine is a sign of good hydration and a healthy urinary tract. However, if they consistently notice clear urine and also have extreme or unusual thirst, it is best to speak to a doctor.

Where does the concentration of urine occur?

medullaThe region of the kidney that is responsible for the generation of concentrated or dilute urine is the medulla (figure 1).

What is concentrated urine mean?

The laboratory will test how concentrated your urine is. More concentrated urine means that there are more solutes and less water in the sample. Solutes are dissolved particles, such as sugars, salts, and proteins. Normal values may vary based on the laboratory used.

Which hormone controls the concentration of urine?

The hypothalamus produces a polypeptide hormone known as antidiuretic hormone (ADH), which is transported to and released from the posterior pituitary gland. The principal action of ADH is to regulate the amount of water excreted by the kidneys.

What causes urine to concentrate?

Urine naturally has some yellow pigments called urobilin or urochrome. The darker urine is, the more concentrated it tends to be. Dark urine is most commonly due to dehydration. However, it may be an indicator that excess, unusual, or potentially dangerous waste products are circulating in the body.

Which is the principal site for concentration of urine?

Sodium and potassium, accompanied by univalent anions, and urea are the major urinary solutes; urea is normally predominant urinary solute during a strong antidiuresis [2;3]. The mechanisms for the independent control of water and sodium excretion are mostly contained within the renal medulla.

What is the healthiest Colour of urine?

If everything is normal and healthy, the color should be a pale yellow to gold. That hue comes from a pigment your body makes called urochrome. The shade, light or dark, also changes.

How do kidneys control urine concentration?

In the presence of ADH, the medullary collecting ducts become freely permeable to solute and water. As a consequence, the fluid entering the ducts (en route to the renal pelvis and subsequent elimination) acquires the concentration of the interstitial fluid of the medulla; i.e., the urine becomes concentrated.

What time of day is urine most concentrated?

Best times to check Morning is when your urine will be most concentrated. So, if your morning urine is a pale, straw color, you’re probably well hydrated and healthy. At bedtime, it should look as clear as water or at least pale yellow.
