๐ง Swelling isn't an aesthetic problem โ it's a biological signal.
When the body retains excess fluids, it's communicating something precise: there's excess acidity in the tissues, an inflammation that can't resolve itself, a lymphatic system under overload. The swelling isn't the problem โ it's your body's temporary solution to a deeper problem.
You wake up with swollen hands. By afternoon your ankles seem to push outward. In the morning you weigh 2 kg less than in the evening. Jeans that fit a week ago won't button today. You drink water and seem to swell even more.
Water retention โ technically called subclinical edema or extracellular fluid retention โ is one of the most common and misunderstood conditions of our era. The conventional response is almost always the same: "Reduce your salt." Sometimes: "Drink more water." Rarely: "Keep your legs elevated."
But if salt were truly the only cause, why do people on low-sodium diets often still have retention? And why do some people eat excessive amounts of salt without retaining a gram of fluid?
The answer is that water retention is a multifactorial phenomenon with precise biological causes that go well beyond sodium.
The Biology of Water Retention
To understand why the body retains fluids, you must first understand how water balance is regulated. The human body is 60-70% water, distributed among three main compartments:
- Intracellular: water inside the cells (about 65% of total)
- Interstitial: water in the space between cells (about 20%)
- Intravascular: water in the blood (about 15%)
The water retention you can see and feel โ the swelling of legs, ankles, abdomen, hands โ is almost always an accumulation in the interstitial space. Fluids have "left" the vessels and haven't been reabsorbed or drained by the lymphatic system.
This happens when the regulatory system is disturbed. And the causes of this disturbance are much more specific than "you eat too much salt."
Pathophysiology of Retention
The balance of fluids between the vascular and interstitial compartments is regulated by Starling's Law: oncotic pressure (linked to plasma proteins, primarily albumin) retains fluids in vessels, while hydrostatic pressure pushes them out. When capillary permeability increases โ as occurs with systemic inflammation โ fluids "filter" more easily into tissues. If the lymphatic system can't drain them quickly, edema accumulates.

The 5 Biological Causes of Water Retention
These aren't alternative theories โ they are pathophysiological mechanisms recognized in the scientific literature:
๐งช Tissue Acidosis
This is the most undervalued and most widespread cause. When tissues are in a state of subclinical acidosis โ due to a diet rich in acidifying foods, chronic stress, excessive physical activity, or insufficient rest โ the body retains fluids as a buffering mechanism: by diluting the excess H+ ions in the tissues, it attempts to restore pH balance. The more acidic the tissues, the more the body retains fluids. The visible consequence is swelling. The solution isn't a diuretic โ it's deacidifying the tissues.
๐ฅ Chronic Low-Grade Inflammation
Pro-inflammatory cytokines (particularly IL-1ฮฒ, IL-6, TNF-ฮฑ) increase capillary permeability, allowing fluids to leave the bloodstream into the interstitial space. Silent chronic inflammation โ sustained by poor diet, gut dysbiosis, oxidative stress โ constantly maintains elevated capillary permeability. The result is diffuse swelling that doesn't respond to simple rest or salt reduction.
๐ Lymphatic System Overload
The lymphatic system is the body's drainage system โ it collects excess interstitial fluids and returns them to the venous circulation. Unlike the circulatory system, it has no pump of its own (the heart): it moves through muscle movement and changes in thoracic pressure during breathing. Sedentary lifestyle, insufficient movement, shallow breathing, and compressive clothing slow lymphatic drainage. The accumulation of undrained interstitial fluids is the water retention you see.
๐ฅฉ Excess Animal Protein and Sodium/Potassium Imbalance
Excess animal protein increases urea production and other nitrogen catabolites, aggravating renal load and tissue acidosis. In parallel, modern diets are typically rich in sodium (table salt, processed foods) and poor in potassium (vegetables, fresh fruit). This imbalance favors retention, because intracellular potassium counterbalances extracellular sodium: without enough potassium, sodium brings more water into the tissues.
โ๏ธ Hormonal Imbalance: Estrogens, Cortisol, Aldosterone
Three hormones directly influence water retention: estrogens (even in men, if there's high aromatization of testosterone due to excess visceral fat or endocrine disruptors), chronic cortisol (which stimulates aldosterone, the hormone that makes the kidneys retain sodium), and chronically elevated insulin (which directly stimulates sodium reabsorption in renal tubules). These hormonal imbalances create a vicious cycle that a simple diuretic cannot break.
"Fighting water retention with diuretics is like emptying a leaking bucket with a spoon: it works while you use it, but the bucket will keep filling until you find the hole."
โ Massimiliano Romeo, Metodo Romeo
The Diuretic Is Not the Solution
Diuretics โ both pharmacological (furosemide, hydrochlorothiazide) and natural (coffee, dandelion, birch) โ work by stimulating the kidneys to expel more water and sodium in urine. The effect is quick and visible: swelling decreases, weight drops. But that's all.
The problem is that diuretics don't address the causes of retention. They don't deacidify tissues, don't reduce inflammation, don't improve lymphatic drainage, don't rebalance sodium/potassium. When their effect wears off, the body restores retention โ often in an even more pronounced way, in a compensatory mechanism.
Chronic use of natural diuretics (like coffee) can actually worsen the problem long-term, as it stimulates cortisol (which promotes retention) and further acidifies tissues.
The Water Paradox
One of the most widespread beliefs is that drinking lots of water worsens retention. It's the opposite. When the body perceives a water shortage (insufficient hydration), it activates water-saving mechanisms at the renal and tissue level. Drinking adequately โ preferably low-mineral water with pH โฅ 7.4 โ signals to the body that water is available and doesn't need to be retained. True hydration, combined with tissue alkalinization, is one of the most effective tools against chronic retention.
The Solution: Three Interventions on Real Causes
1. Deacidify Tissues with Alkalizing Nutrition
Increasing consumption of fresh fruit (especially in the morning), dark leafy greens, sprouts, and colorful vegetables progressively shifts tissue pH toward neutrality. As tissue acidosis decreases, the body spontaneously reduces fluid retention used as a buffer. The perceptible change typically occurs within 2-4 weeks of consistent application.
2. Support Lymphatic Drainage with Movement and Breathing
Brisk walking for at least 30 minutes daily is the most effective and undervalued form of lymphatic support. The contraction and relaxation of leg muscles during walking acts as a "pump" for the lymphatic system. Deep diaphragmatic breathing creates the thoracic pressure variations that move lymph toward collector ducts. Combining daily movement and conscious breathing is more effective than any draining supplement.
3. Rebalance Sodium/Potassium Through Food
Reducing added salt is useful, but more important is increasing potassium: banana, avocado, sweet potatoes, beans, dark leafy greens are the best sources. Potassium counterbalances sodium at the cellular level and promotes the excretion of excess sodium through the kidneys. No need to "count milligrams" โ just shift the balance toward more fresh foods and fewer processed ones.

Conclusion: Swelling Is a Message, Not a Destiny
The body doesn't retain fluids out of spite. It does so because it's trying to protect its tissues from an internal environment that has lost its balance. Water retention is the response, not the problem.
When you work on the real causes โ tissue acidosis, inflammation, lymphatic overload, hormonal imbalance โ the body stops retaining what it no longer needs. Not because you "forced" it with a diuretic, but because it no longer has a reason to.
This is the core principle of Metodo Romeo: the body knows what to do. You just need to stop obstructing it and give it the conditions to do it well.
