Understanding Foam in Urine: When is it a Concern?
Age 24, I've observed a notable increase in the amount of foam in my urine over the past couple of years, compared to what I remember from before. About a year ago, I mentioned this to my primary care physician, who seemed somewhat dismissive of my concerns. Nonetheless, they proceeded to conduct a urinalysis, which returned normal results, indicating no elevated protein levels. I frequently undergo blood tests, and both my eGFR and creatinine levels typically fall within the normal range, although I did experience some fluctuations linked to a bout of mononucleosis a couple of years back, where my eGFR dipped near 70; it currently remains above 100. I suspect that changes in my urological function, likely from aging, are contributing to a stronger urine stream now than in my youth. The foam generally settles down after a few minutes, although occasionally it lingers longer than expected. I make a concerted effort to stay hydrated, even though I don’t always succeed, so I wonder if mild dehydration could partially account for the foaming. This concern is particularly relevant as I'm resuming strength training and planning to increase my protein consumption. I want to ensure that my kidneys are not overtaxed due to any potential underlying issues. Additionally, I have a history of taking 5 grams of creatine daily, paired with plenty of water, which makes me cautious about this, too. Is there a point at which foaming in urine is considered excessive, or does a specific threshold exist that I should be aware of?

Increased foam in urine can often raise questions, especially when it seems unusual or persistent. In your case, since your previous medical evaluations (urinalysis and blood tests) showed normal results, there are a few things to consider to help you determine if this is a cause for concern.
Explanation:
Foaming in urine can occur for various reasons. It's often benign and can result from several factors, including:
- Urine Concentration: If you're dehydrated, your urine becomes more concentrated, leading to increased foaming. Staying well-hydrated can help minimize this.
- Strong Urine Stream: As you've noted, a stronger urine stream can create more bubbles, which can appear like foaming.
- Protein Levels: While your previous tests indicated normal protein levels, persistent foam can sometimes suggest proteinuria (an excess of protein in urine) if it were significantly elevated.
Since you mentioned normal tests, changes in hydration, and urine stream strength could be influencing what you’re observing.
Next Steps:
-
Hydration: Focus on staying consistently hydrated. Aim for at least 8-10 cups of water daily, adjusting as needed based on your activity level and diet.
-
Observe: Keep track of any additional symptoms you may experience alongside the foaming—like changes in urination frequency, swelling, or fatigue. These could provide clues about your kidney function.
-
Protein Intake: As you increase your protein consumption with renewed strength training, monitor how your urine appears. If foaming increases significantly with dietary changes, it may call for further assessment.
-
Regular Check-ups: Consider setting a routine for monitoring kidney function tests. If you notice any significant changes in your urine or related symptoms, it would be wise to bring those up with your healthcare provider.
If you continue to have concerns or if foaming increases despite healthy habits, reaching out to a healthcare professional for further assessment might provide peace of mind. You're doing well by paying attention to your body and seeking clarity.

Rash on the Dorsal Side of My Hands
A 24-year-old male, standing 5'3" and weighing 125 pounds, is not currently taking any medications. While I do not smoke, I am often exposed to secondhand smoke from those around me, and I have recently spent time in an environment where a significant amount of unpleasant smoke is produced due to casting activities. For approximately three weeks, I have been experiencing a rash on the backs of both my hands. I initially became aware of it after working on my car's engine. The rash has led to dryness and itching, and I took a photo after my shower today, highlighting the redness that has become particularly noticeable. What are some effective treatments for this condition?
Understanding Symptoms of Salmonella: What to Do Next
My boyfriend, who is 26, experienced a fever that peaked at approximately 99.5°F yesterday morning. Thankfully, after resting and taking NyQuil, his fever subsided by this morning. However, he has been dealing with severe abdominal pain and persistent diarrhea since last evening, which has not shown much improvement. He has been making frequent trips to the restroom, nearly every hour throughout the night and again today. While I initially thought he might be improving since the fever has decreased, I became alarmed upon noticing bright red blood in his stool and on the toilet paper after he wipes. It has been around 40 hours since the fever began, and my concern has heightened now that blood has appeared. I’ve come across some online information suggesting these symptoms might be typical for salmonella infections, and I’m uncertain whether we should seek medical attention immediately or if it’s advisable to wait another day or two to see if his condition improves. I realize that consulting a doctor as soon as possible would be the best course of action. However, he currently lacks insurance, which makes him hesitant to get checked right away. Any guidance on this matter would be greatly appreciated, thank you.
Navigating Alcohol Challenges
My partner has recently developed issues with alcohol. Over the past year, he has been consuming significant amounts—roughly two bottles of distilled spirits each week, in addition to beer. A decade ago, he struggled with inhalants and even faced near-fatal consequences, but he had maintained sobriety until he turned to drinking. He believes he has plenty of time before the effects of alcohol will manifest. How long can he continue this way before it becomes a serious problem? He is a 53-year-old male, weighing 325 pounds, standing at 5 feet 11 inches, and he is currently on medication for hypertension. Although we plan to separate later this year, it’s clear that this situation will have an impact on our three children.
Exploring MRI vs. CT Scans for Headache Evaluation
Greetings! My husband, aged 33, has been suffering from persistent headaches for the past couple of months. These headaches predominantly affect the right side of his head, specifically behind his eye, and tend to surface several times each week, particularly in the evenings. Relief is often found with extra-strength Tylenol, although there have been instances where the pain has persisted throughout the night and into the following day. The discomfort intensifies when he bends over or makes any sudden movements. In an effort to manage his symptoms, his doctor recommended magnesium supplements, which initially seemed to reduce the frequency of the headaches for a few weeks; unfortunately, the relief was only temporary as the headaches returned. He underwent blood tests, revealing that all results were normal apart from a minor elevation in his white blood cell count, which the physician indicated could potentially relate to a bacterial infection. My husband experienced a mild cold during this time, yet the doctor reassured us that these two issues were unrelated. Although he takes a multivitamin designed for men, he has maintained that routine long before these headaches began. For additional context, he sustained a moderate traumatic brain injury in his early twenties, which resulted in a blackout and a loss of about two weeks of memory. Fortunately, he has been doing well since that incident. With the resurgence of his headaches, his doctor has recommended a CT scan. However, I’m curious if opting for an MRI might be a more suitable choice. He has undergone approximately five CT scans in total due to his previous TBI and a back injury. I recall my doctor expressing concern over frequent CT scans at a young age, which has led me to seek guidance. My main inquiry is: would an MRI provide sufficient imaging quality to help determine the underlying cause of his headaches?
Persisting Chills Without Fever for Three Weeks After a Cold
Greetings! I'm a 30-year-old male dealing with a rather unusual situation, and I'm at a loss for what to do next. As mentioned in the title, I recently experienced a cold, which presented all the expected symptoms, but the chills have lingered. It's been around three weeks now, and I still feel cold despite wearing multiple layers and having the heater running in my home. Strangely, throughout this episode, I haven't had a single fever. I consulted my primary care physician, who also seemed puzzled by my symptoms. She has requested some blood tests which are scheduled for Monday, even though I had blood work done three months ago that showed normal results. Does anyone have insights into what might be causing this? I understand there could be various explanations, but I'm unsure how to proceed. I am not currently on any medications and don't have any known chronic health conditions. Any guidance on how to tackle this issue would be greatly appreciated! 🙏
