Acid reflux, often labelled GERD when chronic, is widely misunderstood. In mainstream thinking it is caused by too much stomach acid, but from a Natural Hygiene perspective the problem is not excess acid. The problem is irritation, stagnation and pressure in a digestive system that has become overwhelmed. Reflux happens when the stomach is unable to process the volume or complexity of food inside it. The body then uses upward pressure to relieve itself, sending acid or partially digested material back toward the oesophagus. This is not a malfunction. It is the body’s way of protecting itself from further overload.
The stomach is designed to break down simple, natural foods. Fruits and vegetables digest cleanly and quickly, leaving little residue. Modern eating patterns, however, impose a heavy burden. Cooked fats, oils, animal products, processed foods, fried meals and complex combinations of starches and proteins sit in the stomach far longer than nature intended. These foods ferment, release gases and increase internal pressure. When the pressure becomes too great, the lower oesophageal sphincter opens to relieve it. The burning sensation people feel is not because the body has made a mistake but because the stomach’s contents are not meant to linger and decay.
Reflux is often worse at night. This is not accidental. The digestive system slows down as the body prepares for rest. When a heavy or late meal is still sitting in the stomach at bedtime, digestion becomes sluggish. The stomach struggles to process the food, gases build, and reflux occurs. Lying down removes the help of gravity, making it even easier for contents to move upward. Natural Hygiene teaches that the evening is a time for restoration, not digestion. Eating earlier and lighter gives the stomach the space it needs to complete its work before sleep.
Another major factor is the strength of the oesophageal valve. Contrary to popular belief, the valve is not “weak” by accident. It relaxes when the stomach is too full, too pressurised or too irritated. Inflammation from acidic or spicy foods, alcohol, coffee, fried foods or overeating can irritate the valve and cause it to open prematurely. The body does this to protect deeper tissues from being damaged. As the internal terrain becomes cleaner and calmer, the valve’s function improves naturally.
Hydration plays a significant role as well. Proper stomach acid requires a well-hydrated body. When someone is dehydrated, the stomach acid becomes more concentrated but less effective. The stomach then struggles to break down food, leading to fermentation and reflux. Hydration should come primarily from raw fruits and vegetables rather than large amounts of plain water consumed with meals. Drinking water with food dilutes digestive juices and can worsen symptoms. Eating high-water foods before the meal prepares the digestive tract more effectively.
Stress also contributes significantly to acid reflux. When the body is in a sympathetic, fight-or-flight state, digestion shuts down. Blood is diverted from the stomach to the muscles and brain. If food is eaten in this state, the stomach cannot properly process it. This leads to fermentation, gas and acid movement. Calm breathing, slower meals and emotional ease are essential for proper digestion. People often notice that reflux worsens during stressful periods regardless of what they eat.
Posture and movement also influence reflux. Sitting slouched after eating compresses the stomach, pushing its contents upward. Light walking after meals stimulates digestion and reduces gas buildup. Sedentary eating habits make it harder for the body to manage heavy or complex meals.
Reflux is often treated with acid blockers, but these suppress the body’s natural digestive processes. The stomach acid that seems problematic is actually essential. Without proper acid levels, digestion weakens further, leading to more fermentation and more reflux in the long term. Natural Hygiene encourages supporting rather than suppressing the body. By simplifying eating habits, the digestive system restores itself without intervention.
Healing begins with giving the stomach rest. Fasting, or even short periods of fruit-only meals, reduces irritation and pressure almost immediately. Fruit digests quickly and does not ferment in the stomach when eaten alone. This allows the stomach lining to heal, inflammation to reduce and pressure to normalise. Over time, reflux episodes become less frequent and less intense.
Food combining is another important factor. Proteins and starches require different digestive environments and should not be eaten together. When combined, they linger in the stomach, causing fermentation and gas. A fruit-based meal or a simple meal of one type of food digests far more efficiently. Natural Hygiene emphasises simplicity because the body thrives on it.
Reflux can also be a sign that the liver and gallbladder are sluggish. When bile flow is impaired, fats are not digested properly and this increases stomach workload. Cleansing the liver through rest, light eating and avoidance of heavy fats often improves reflux significantly.
Acid reflux and GERD are messages, not malfunctions. They reveal where irritation, stagnation and pressure have built up over time. When we respond with rest, simplicity and hydration, the digestive system calms down. The burning fades, digestion becomes smoother and the stomach regains its natural rhythm. The body always communicates its needs. Reflux is simply one of the ways it asks for relief and renewal.
