What Causes Knee Edema?
Knee edema can have various causes, ranging in severity from 'very minor' to 'life-threatening'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose knee edema, we could:
- Research the topic
- Find a doctor with the time
- Use a diagnostic computer system.
The process is the same, whichever method is used.
Step 1: List all Possible Causes
We begin by identifying the disease conditions which have "knee edema" as a symptom. Here are eight of many possibilities (more below
- Kidney Disease
- Alcohol Consequences
- Low Progesterone
- Nat Mur Need
- Aspartame/Neotame Side-Effects
- Excess Salt Consumption
- Protein Deficiency
- Hormone Imbalance
Step 2: Build a Symptom Checklist
We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:
very early puberty onset
an enlarged nose
infrequent daytime urination
recent oily hair
excellent HDL cholesterol level
minor joint pain/swelling/stiffness
shortness of breath when at rest
... and more than 80 others
Step 3: Rule Out or Confirm each Possible Cause
A differential diagnosis of your symptoms and risk factors finds the likely cause of knee edema:
|Nat Mur Need
|Excess Salt Consumption
* This is a simple example to illustrate the process
Arriving at a Correct Diagnosis
is our online diagnosis tool that learns all about you through a straightforward process of multi-level questioning, providing diagnosis at the end.
Do you have edema of the knees? To rate its severity, press firmly with a finger for 5 seconds and note the approximate depth of the indentation or length of time to return to normal.
→ No / don't know
→ Slight: 5mm (1/4 inch) depth, immediate return
→ Minor: 8-10mm (1/2 inch) depth, 10-15 seconds
→ Moderate: 11-20mm (3/4 inch) depth, 15-30 seconds
→ Severe: Over 20mm (1 inch) depth, over 30 seconds
Based on your response to this question, which may indicate edema of the knees, The Analyst™

Progesterone Low or Estrogen Dominance
|Progesterone has also been used in the treatment of idiopathic edema under the premise that some women with idiopathic edema either do not ovulate or have a luteal phase deficiency. |
Ovarian function was investigated in 30 women with postural idiopathic edema by measuring plasma estradiol and progesterone levels between the 21st and 23rd days of the menstrual cycle. Plasma progesterone concentrations were found to be lower than 5ng/ml in 53% of the cases and lower than 10ng/ml in 83%. The ovarian dysfunction most frequently observed was inadequate corpus luteum, i.e. progesterone deficiency with normal plasma estradiol levels. In virtually all patients the initial disorder in capillary permeability, as evaluated by Landis' test, was fully corrected by progesterone administered orally. However, clinical improvement was less marked with treatments of short duration (2-3 consecutive cycles). In view of the complex cause of the disease, combined treatments in which progesterone might well play the major role are usually required. [Presse Med 1983 Dec 10;12(45): pp.2859-62 (translated)]
|When protein (especially albumin) levels in your blood go too low, the colloidal osmotic pressure will decrease and allow fluid to escape from blood vessels into your tissues, resulting in edema or swelling of the hands, feet, ankles, knees and/or belly.|Hormone Imbalance
|Hormones regulate the amount of interstitial fluid surrounding our body's cells. A hormone imbalance can result in too much interstitial fluid, and thus edema.|Anorexia / Starvation Tendency
|Semi-starvation can cause edema. People with eating disorders may interpret the puffiness of edema or any changes on the scale as weight gain or getting "fat" and may panic and purge or take laxatives even more.|Atrophic Gastritis
|Edema may be due to low levels of circulating proteins from poor protein digestion.|
