Hello doc,
As the title say, I am experiencing foamy urine. I noticed it around April (2023) last year, I do not know when it begun. It is true foam not just bubbles, sometimes less sometimes more. Usually, after a meal it is more and after exercise too. At that time, I had a bad shoulder injury, and I was using advil topical and sometimes nsaids. I do not know if that was the reason for the foamy urine. Also, I was and am experiencing a lot of stress due to other factors but also due to the foamy urine. I am getting obsessed about it, and it is all I can think of. My shoulder got better after the shoulder rehab template. Now I am running the hypertrophy II template with no discomfort, training 6 days a week. I wrote about this in the fb group too. I went to two different GPs in June and September. The results are the following,
1st GP (June 2023): serum haematology, liver etc all fine. Sodium, potassium within normal range.
Creatinine = 1.25 mg/dl (upper limit 1.17)
Albumin (serum) = 47 g/l (35-55)
Fasting glucose = 5.4 mmol/l (4.0-6.4)
Urine (first void of the day but hours after I had woken up, was foamy):
Total protein = 0.06 g/l (<0.1)
Creatinine = 17.3 mmol/l (5-10)
PCR = 3 (<30)
For the test I had two days of rest and one day off creatinine.
2nd GP(September): He ran lots of tests. Kidney, upper and lower front belly ultrasound normal. I had high blood pressure at the doc (I think 14/8) and he told me to monitor at home for a week. I was taking 2-3 measurements at midday by following your instructions from an article. I was always below 12/8.
Blood work: RA factor negative (for the shoulder, I asked it because I was afraid), anti-something for RA also negative. Anti-dsdna for lupus non-existent. CRP 1.8 mg/L (0-5). Glucose normal, Cholesterol 226 mg/dl (<200) (I was on a bulk, maybe a dirty one. Maybe related to kidneys(?)). Triglycerides 63 mg/dl(<150). HDL 55 mg/dl (40-85). SGOT,SGPT,γ-GT all normal. ALP, LDH normal. Ferritin, Iron normal.
Kidneys (blood work): Urea normal, albumin 4.7 gl/dl (3.5-5), Total protein 7.5 g/dL (6.3-8.6), creatinine = 1.18 mg/dl (0.6-1.3), Cystatin C= 0.78 mg/l (0.31-0.79 mg/L weird range(?). I personally asked the lab for cystatin c and they had no clue about it except one person).
Urine (first void of the day, was foamy): microalbumin = <5 μg/mL (<20), creatinine= 144,8 mg/dl (22-392). UACR = <3.5 mg/g (<20) . Urine analysis with dipstick clear and negative to protein with red blood cells in the urine at 0 1.
Urine 24hour collection (that day I had bad sleep, and low mood. I only ate two protein meals.)
Urine volume = 2880 mL (drank lots of water, also when I do not sleep well i urinate more)
Creatine Clearance = 139 mL/min (85-125)
Protein = 141.1 mg (<150) (kept the collection outside fridge in room temperature and I read that it might increase protein)
For that test, I was off exercise and creatine for 6 days.
I am male 28yo, 170cm, 80 kg, body fat 15-20%, waist 77 cm. My creatinine for years was between 1.2 to 1.4. I still experience foamy urine. I understand that it might be difficult to answer in a forum post. When I asked the second GP what I should do in the future, he told me that I do not need further testing. The first GP told me that the foam might be from my high creatinine in the urine which I doubt. What should my steps be next? This thing is consuming all my mental energy. I feel in danger all the time.
