Serum creatinine back to 2.0 mg / dL. Why?

My most recent blood test had a pleasant surprise. According to the results, my blood creatinine level is back to 2.0 (pretty much where it was when I was first diagnosed with CKD, 15 years ago). This was a surprise as tests during the last fives where all above 2.5.

I don't think my kidney function has improved but this result may at least mean it's not worsening as much as I thought. My current theories for the results are:
1. I have been exercising less lately. Perhaps the elevated creatinine levels were due to doing more exercise.
2. Inaccurate test results!

The next time I test, I'll try doing more exercise beforehand to see how much that seems to impact the results.


Current lifestyle/diet: No meat or chicken, low cheese/milk (some yogurt), low wheat, oats+berries+chia+olive oil for breakfast, fish a few of times a month, commonly eat: lentils, vegetables, fruits, potatos, rice, corn tortillas, peanuts,

2021 Serum Creatinine rising

Since 2016 my serum creatinine has been rising at a surprisingly constant rate (see graph), suggesting a progressively declining kidney function, reaching a peak of 2.7mg/dL (Estimated GPR 26 mL/min/1.73m2, stage IV) 6 weeks ago (13-May-2021).

Shocked and depressed at this decline I met with a new nephrologist to see what she recommends to reduce the rate of decline. She didn't really offer any new advice but ordered more tests which I did on 23-Jun-2021. She also weighed me, 78kg, which is lighter than I expected (I'm 1.82m tall). I have been exercising almost daily the last year or so, so I guess I've lost a few kilos of body fat.

The tests on 23-Jun-2021 showed a creatine level of 2.4 ml/dL which is a change in the right direction. The things I did between the two last tests which may have impacted the result were:
- Watch my diet carefully, eating very few animal proteins and especially avoiding cheese (high salt).
- Meditate with afirmations in the form of questions like "Why is my serum creatinine at 1.8?" (I didn't hit that target obviously), "Why do my kidneys work so well?", "Why are my kidneys no longer inflammed?", etc.

One of my previous nephrologists said that reducing protein consumption can reduce the creatinine reading (which wouldn't necessarily mean any improvement in kidney function) but this nephrologist said that the amount of creatinine released into the blood is determined more by muscle mass (which may have increased slightly over the last year or so, as I've done more exercise. Certainly my muscles are stronger now than say 2 years ago).

I also tested for Bicarbonate and Vitamin D. Both were within normal range, though the Vitamin D was on the low side and I certainly have the symptons of Vitamin D deficiency (fatigue).

Chronic Kidney Disease Research Community

Some kind of online community for Chronic Kidney Disease is being created. My understanding is that people can share their data and experiences and perhaps receive recommendations. Click the following link to find out more and sign up: https://stuff.co/s/icjdGZMQ

2019 Blood test results - more kidney function degradation :(

I have been suffering on and off from intestinal inflammation over the last four months, causing abdominal pain and discomfort. The initial attacks seem to have been triggered from eating a peanut and dried fruit trail mix (on four occasions after eating said trail mix I had symptoms within a few hours / next morning) but it's not clear whats causing the symptoms to remain three months later. An ultrasound shows no other problems except the inflammed small intestine. A specialist ordered lab tests (which I was overdue for anyway), antiparasite medication (which had no effect), and an anti-inflamation medicine, which also has had little effect. Unfortunately the lab tests show a ~10% degradation of kidney function compared to tests a year ago: I feel this degradation of kidney function may be related to the the intestinal inflammation (maybe whatever is causing this is also causing kidney inflammation) and so hope to get this resolved as soon as possible and start a renewed effort to improve my overall health with daily exercise and more careful attention to diet! Will test again after a few months of dedicated wellness activies and see if it shows any improvement.

Kidney degradation not inevitable?

The following article says a recent study shows that while kidney function tends to decline with age in more developed societies, this is not necessarily the case in less developed societies. That is, it seems like there may be something (or many things) about our "advanced" lifestyle which causes kidney degradation with age. No clues as to what that might be yet but adopting a more "primitive" diet (less processed food, more fruits and vegetables) certainly seems like it would probably benefit the kidneys.

Since being diagnosed with chronic kidney disease (CKD) almost 10 years ago I have fortunately so far managed to avoid further measurable kidney degradation. My diet has basically been:
- Relatively small amounts of animal proteins (no beef/pork/chicken/etc., fish/seafood maybe twice a month, eggs once week, yogurt and cheese a couple of times a week, no milk).
- Limited wheat (I found that wheat seems to cause me abdominal swelling).
- Lots of fruit, vegetales and nuts (bananas, avocados, broccoli, carrots, apples, almonds, unsalted peanuts, beetroot, lettuce, tomato, beans, etc.).
- Low sugar and salt (no added salt in cooking. Avoid high salt foods).
- A certain amount of starchy foods every day: Rice, corn, oatmeal, sweet potatoes, potatoes.

Surefire way to reduce blood pressure without drugs

Almost by accident I've discovered that running temporarily reduces my blood pressure significantly: I've measured by before and after blood pressure 4 times now and in each case it's dropped from around 130/80 to around 115/70 (or less) after running ~2km (~1 mile) (which is around 10 minutes running for me). The effect only lasts a few hours but I'm guessing that running twice a day could help a lot in keeping the pressure down, and thus reduce the damage to the kidneys from high blood pressure. My only problem is that as well as chronic kidney disease, I also suffer from chronic laziness... but I guess it's just a matter of acquiring the habit.

The dangers of Internet diagnosis

The last month I have been suffering horribly from itchy skin, mostly in the legs. Because there were no visual signs at first, I self-internet-diagnosed the itchiness as a symptom of poor circulation (a few months ago I was diagnosed with a probable small blood clot in one of my legs). My doctor for circulation issues is located about an hour's drive away and in any case had no appointments immediately available so I self-medicated by doing exercise (to improve circulation) and applying moisturizing cream to reduce the itchiness. Unfortunately, over the weeks, things worsened until the itchiness spread all over my body, in patches of visible spots, and so uncomfortable it was interfering with my work and leisure. Now it was obvious that this must be some kind of skin issue and probably not related to circulation or my kidney disease (which can also cause itchiness in the late stages). I called my usual dermatogist. Next available appointment in 6 weeks. I'd probably commit suicide by then because the itching was driving me crazy. Managed to get an appointment with a general practitioner who swiftly diagnosed the problem as scabies, a microscopic parasite whose larvae burrow into the skin. While relieved to find I had a treatable condition, I felt like such an idiot for suffering for so long just because of my general reluctance to organize a visit to the doctor. Moral of the story: SEE AN EXPERT as soon as things start getting worse! Second moral: Those of us who have easy access to healthcare are unbelievably lucky compared to the most of the world's population. We should appreciate that and not take it for granted.
