Why Medical Literature Lacks Internal Allergy to Water

Have you ever heard of an allergy to water? If not, we are here to explain why such a phenomenon is impossible within the realm of current medical knowledge. In this article, we explore the reasons why there is no medical literature on internal allergies to water. We will delve into the nature of allergies, the physical properties of water, and the limitations of the human immune system.

Understanding Allergic Reactions

First, let's start with a general understanding of what an allergic reaction is. Allergic reactions stem from the immune system’s response to specific substances, known as allergens. These reactions vary in severity and can range from mild discomfort to life-threatening anaphylaxis. However, the human body's composition and its interactions with water present unique challenges that make the concept of a water allergy nonsensical.

Impossible Allergen: Water

Water cannot be considered an allergen because an allergic reaction requires the immune system to recognize and respond to a substance. Water, however, comprises more than half of the body's mass and is integral to nearly every biological process. If the immune system were to react to water, every cell in the body would be compromised, leading to unviable biological functions. This is why saying that there can be an allergy to water is incorrect.

Size and Immunological Invisibility

Let's break down why water is too small to be detected by the immune system. Water molecules, consisting of two hydrogen atoms and one oxygen atom, are incredibly tiny. For context, an illustration of an immunoglobulin (IgG) shows the knobbly little contours of peptide domains that are far larger than water molecules. Even in the context of the ubiquitous serum protein albumin, where we see some specific peptides up close, the molecules are still much larger than single water molecules.

Take a look at this schematic representation of a single instance of leucine, one of the smaller amino acids. It is evident that the atoms in a single water molecule are too small to be recognized by the immune system. The sheer size difference makes it practically invisible on an immunological scale, as it would not be capable of being bound by the glycoprotein structures that characterize immune system components.

The Scale of the Problem

On an architectural level, allergies involve molecular changes in immune mediators due to the presence of an allergen. This process cannot occur with water due to its microscopic size and the enormous disparity in scale. The immune system relies on specific molecular recognition to trigger a response, and there is no possible way for this recognition to occur with such an incredibly small molecule like water.

Biological Necessity of Water

Moreover, the body is composed of about 70% water, and maintaining this level is essential for life. Natural methods for water balance include ingestion and excretion by the kidneys. An allergy to water not only contradicts the fundamental biological necessity of water but also would make survival impossible. Any immune response to water would disrupt every cell and organ in the body.

Thus, it is clear that medical literature will never address internal allergies to water. The immune system is not structured to recognize such a minuscule substance, and doing so would be biologically nonsensical and harmful.
