Dark yellow urine?


I usually don't have the habit of drinking plain water, but I often prepare instant drinks (coffee or milk tea) and occasionally consume beverages available on the market (but not frequently).
My urine tends to be quite yellow four to five times a day, but on busier days, I notice that when I skip meals, it appears clearer.
Additionally, my urine is very yellow every morning upon waking.
Sometimes, I experience tightness and soreness in my lower back.
I previously underwent a physical examination, and the urinalysis showed no hematuria or other urinary issues; however, my albumin and total protein levels (8.1) were slightly above the normal range.
The yellow urine phenomenon started about one to two months after the physical exam and has persisted for nearly two months.
I would like to ask the doctor if there is a problem and whether I should visit a hospital.
Should I see a nephrologist or a urologist? Thank you.

Mr.
Bai: Hello! Your main issue is to drink more water, approximately 2000 cc per day.
If you still have problems, you can consult either a urologist or a nephrologist.

More Info


Understanding dark yellow urine can be concerning, especially when it persists over time. The color of urine can be influenced by various factors, including hydration levels, diet, medications, and underlying health conditions. In your case, the dark yellow color of your urine, particularly after not consuming enough fluids or food, suggests that you may be experiencing dehydration. When the body is dehydrated, urine becomes more concentrated, leading to a darker color.

You mentioned that you do not typically drink plain water but consume instant drinks like coffee or milk tea. While these beverages do contribute to your fluid intake, they may not be as effective as water in hydrating your body. Caffeine, found in coffee and some teas, can have a diuretic effect, which means it can lead to increased urine production and potentially contribute to dehydration if consumed in excess without adequate water intake.

The fact that your urine appears clearer when you are well-hydrated (e.g., after eating or drinking more fluids) is a positive sign, indicating that hydration does play a significant role in the color of your urine. However, the persistent dark yellow urine, especially upon waking, could also indicate that your body is not adequately hydrated overnight. This is common, as urine tends to be more concentrated in the morning after several hours of fasting during sleep.

Regarding your protein levels, you mentioned that your total protein level is slightly elevated. While a mild increase in protein levels can occur due to dehydration, it can also indicate other underlying issues, such as kidney function problems or other systemic conditions. Since you have experienced persistent changes in your urine color and have elevated protein levels, it is essential to follow up with a healthcare professional.

In terms of which specialist to see, both nephrologists (kidney specialists) and urologists (urinary tract specialists) can address your concerns. However, given your symptoms and the protein levels in your urine, starting with a nephrologist may be more appropriate. They can evaluate your kidney function, assess for any underlying conditions, and determine if further testing is necessary.

In summary, here are some recommendations:
1. Increase Hydration: Aim to drink more water throughout the day. This can help dilute your urine and may improve its color. Consider setting reminders to drink water regularly.

2. Monitor Symptoms: Keep track of any additional symptoms you may experience, such as changes in urination frequency, pain, or swelling. This information will be helpful for your healthcare provider.

3. Follow Up: Given the persistence of your symptoms and the elevated protein levels, it is advisable to schedule an appointment with a nephrologist. They may recommend further tests, such as blood tests to assess kidney function, urine tests to check for protein levels, and possibly imaging studies if indicated.

4. Dietary Considerations: Evaluate your diet and consider incorporating more hydrating foods and beverages. Foods with high water content, such as fruits and vegetables, can also contribute to your overall hydration.

5. Regular Check-Ups: Regular health check-ups can help monitor your kidney function and overall health, especially if you have risk factors for kidney disease.

By taking these steps, you can better understand your symptoms and ensure that any potential health issues are addressed promptly.
