Treating the whole person, not just the symptom

Two different questions

Imagine two people with the same headache. A modern clinic will usually ask what is this symptom, and what stops it? It looks for the diagnosis and treats it, often with a drug aimed at one target. This is extremely effective for infections, fractures, heart attacks and many other problems.

Classical Islamic medicine asks a wider question: what is happening in this person's body as a whole that allows this symptom to appear? The headache is seen as one signal from a body whose digestion, sleep, temperament, habits and surroundings all matter. The physician looks for the cause underneath, and works on it with food, lifestyle and gentle remedies before reaching for anything stronger.

To be fair to modern medicine: it is not blind to the whole person. Family doctors, dietitians and lifestyle medicine all work this way, and doctors do ask about your diet and sleep. But the system is built around short visits, specialists and a prescription, so the "whole person" often gets the least time. The traditional approach puts it first.

Diet comes first

In this view food is the first medicine and the first cause of illness. Physicians of the Islamic golden age wrote at length on regimen. Ibn Sina opens his discussion of health in the Canon of Medicine with the essentials of daily life: air, food and drink, movement and rest, sleep and waking, what the body keeps and what it expels, and the emotions. Al-Razi is reported to have advised treating with diet first, medicines only if diet fails, and a single drug rather than a mixture whenever possible. A saying attributed to al-Harith ibn Kalada, a physician of the early Arabs, sums up the idea: "the stomach is the house of disease, and dieting is the head of every cure." The Qur'an gives the same principle for eating:

Modern research agrees about the weight of diet. Poor diet is among the leading risk factors for illness and early death worldwide, through heart disease, type 2 diabetes, some cancers and obesity. Many of the chronic problems that clinics manage with lifelong tablets are shaped by what we eat every day.

A practical version of the traditional approach to food:

• Eat less than you can. Stop before you are full.
• Eat real food. Dates, olives, barley, lentils, milk, honey, vegetables and fish are what the classical texts recommend, not packets and sugary drinks.
• Eat in season and in line with your climate: lighter in summer, warmer in winter.
• Eat slowly and sit down. Do not eat again until the last meal has been digested.
• Notice what your body says after each food: heaviness, bloating, energy, sleep.

Then odor: reading the signs the body gives

Classical physicians did not have blood tests. They read the body directly. They checked the pulse, the tongue and the color and smell of urine, stool, sweat and breath. A change in a person's smell was a clue that something inside had shifted, usually in digestion. This is why odor sits next to diet in the traditional approach: what you eat comes out in how you smell, and how you smell tells you about what is happening inside.

Modern medicine confirms that this is more than folklore. Some smells are genuine diagnostic signs:

• A fruity or nail-polish smell on the breath can signal ketones in uncontrolled diabetes, which is an emergency.
• An ammonia or fishy smell on the breath can accompany kidney failure.
• A musty, sweetish smell can accompany serious liver disease.
• Persistent bad breath most often comes from the mouth, but can also come from the sinuses, tonsils or stomach.
• Strongly sour or foul-smelling stool or a sudden change in urine smell can point to digestion problems, infection or dehydration.

Classical medicine gave smell and cleanliness real weight too, as part of prevention. Ibn Sina is credited with perfecting the distillation of rose water and aromatic essences, which were used in medicine as well as perfume.

• Cleaning the mouth and teeth with the miswak and herbal powders was a standard part of daily regimen in the classical texts.
• Fragrant waters and herbs were used to freshen the body and the air of the home, and were thought to lift the spirits.

Where each approach is strongest

Classical physicians never saw the two approaches as rivals. Ibn Sina's Canon is a book of regimen, of drugs and of surgery together, and the great hospitals of Baghdad, Cairo and Damascus treated acute illness with medicines and procedures. Al-Razi himself directed hospitals in Rayy and Baghdad. If you have chest pain, a high fever, a serious infection or an injury, you go to a hospital. If you are well, or have mild complaints, or want to prevent illness, you start with the foundations.
