Ayurvedic medicine is one of the world’s oldest medical systems. This holistic approach to medicine originated in India over 3000 years ago. The word Ayurveda means “the science of life” and is based on the idea that each person has interconnected life forces that influence health and well-being. Ayurveda focuses on the balance between body, mind, and spirit. The idea of this ancient practice is to maintain balance in the body, mind, and spirit through prevention of disease, herbal remedies, and the correction of imbalances in the body’s energies.
Ayurveda teaches that balance is the natural order and imbalance is disorder. According to Ayurvedic philosophy, three vital energies, known as doshas, influence a person's health and wellbeing. The three doshas are vata, pitta, and kapha. Vata is associated with the flow of movement in the body and mind. Pitta is responsible for digestion, hormones, and metabolism. Kapha holds everything together and is associated with structure, stability, and endurance. Ayurveda teaches that each person has a unique balance of these doshas, and maintaining that balance helps support the body’s natural defense systems and resist disease.
In Ayurveda, treatment is individualized based on the individual’s unique balance of the doshas. Practitioners evaluate these doshas along with overall health, lifestyle, and symptoms before recommending therapies. Rather than focusing on treating illness after it occurs, prevention of disease is emphasized by maintaining balance and supporting the body’s natural ability to stay healthy. Treatment commonly includes dietary changes, herbal medicines, yoga, meditation, breathing exercises, and lifestyle routines modifications tailored to the individual.
In modern biology, a useful comparison to Ayurveda is homeostasis within the body. Homeostasis is the process by which the body maintains stable internal conditions despite changes in the internal or external environment. When normal conditions are disrupted, the body triggers physiological responses to restore balance and medications or other therapeutic interventions can support this process. Although Ayurveda and modern Western medicine use different approaches to understanding health, both recognize that maintaining balance within the body is essential. Modern biology provides scientific explanations for many physiological systems involved in maintaining homeostasis, including metabolism, hormone regulation, the gut microbiome.
The biological concept of homeostasis is a core principle in modern biology and is essential for survival. These processes include negative and positive feedback mechanisms. Negative feedback tries to counteract or reverse the unwanted changes from the environment to restore balance. It does this through regulating blood pressure, body temperatures, fluid levels, and oxygen levels. In contrast, positive feedback strengthens a response until a specific outcome is achieved. Examples of this are labor and delivery, blood clotting, and some immune responses. Multiple body systems work together to maintain homeostasis. The nervous system utilizes the parasympathetic system to relax the body and the sympathetic system to trigger the “flight-or-fight” response when the body is in danger. The respiratory and the cardiovascular systems assist in maintaining oxygen levels and transporting throughout the body, respectively. The endocrine system produces hormones that act as slow-acting chemical messengers to initiate or stop certain processes. These are just a few examples of what systems contribute to homeostasis. Understanding homeostasis demonstrates how interconnected the systems of the body are. Tying the concept of homeostasis to Ayurveda, shows the similarities that there are between balancing the body. Even though they are different concepts, both emphasize the importance of maintaining internal stability to support health and wellbeing.
While Ayurveda emphasizes maintaining balance within the body, modern biology helps explain how processes like metabolism contribute to this balance and how disruptions can affect overall health. Metabolism consists of chemical reactions that allow the body to obtain and use energy, build and repair tissue, and maintain essential functions. By exploring different metabolic pathways, we can better understand how the body maintains balance and how disruptions in these processes contribute to disease. To maintain balance and homeostasis, different metabolic processes function at different rates because the body uses energy differently throughout the day and with different activities.
Metabolic disorders are any condition that affects how the body uses energy to function. These disorders can be acquired or inherited. A common acquired metabolic disorder is Type 2 Diabetes Mellitus (T2DM). T2DM represents a loss of metabolic homeostasis and is characterized by hyperglycemia due to insulin resistance, inadequate insulin production, or excessive glucagon secretion. Having too much sugar in the body is a factor in the progression of T2DM and can cause complications. The main thing that is affected is the function and mass of pancreatic beta cells.
Pancreatic beta cells are the sole physiological source of insulin. In T2DM, chronic insulin resistance increases the demand on these pancreatic beta cells which eventually leads to losing mass and secretory competence. In healthy beta cells, when blood glucose levels rise, glucose will enter the beta cell and break down to produce ATP in the mitochondria. As ATP levels increase, it causes a change in the cell to allow calcium to enter. The presence of calcium then triggers the release of insulin. The more glucose in the bloodstream, the more ATP produced, and the more insulin released. If the mitochondria in the cell are damaged or do not work properly, the beta cells cannot release insulin in response to increased levels of glucose, causing an imbalance and hyperglycemia.
This example of metabolic disruption demonstrates how the body can be affected and how it tries to maintain metabolic homeostasis. It is important to have proper metabolic regulation in maintaining overall health. However, metabolism is only one part of the body’s complex internal environment. There are different body systems and factors that contribute to the maintenance and balance of homeostasis which includes the gut microbiome that plays a role in digestion, metabolism, and immune function.
The importance of a healthy gut microbiome is a concept where modern biology and Ayurvedic medicine overlap. In Ayurvedic medicine, the dosha, Pitta, is associated with digestion, hormones, and metabolism. Ayurveda emphasizes that proper digestion is central to overall health and the accumulation of undigested or improperly digested food contributes to illness. Because of this, diet plays an important role in Ayurvedic approaches to treatment. In modern biology, it is recognized that the gut microbiome is important for metabolism, immunity and communication with the gut and brain. The gut microbiome consists of a diverse community of microorganisms that live in the digestive tract and interact with the body. These microorganisms assist in stimulation and regulation of the immune system, breaking down of food, and synthesizing certain vitamins and amino acids. A balanced and diverse gut microbiome is critical for maintaining health and balance. A good diet and lifestyle helps promote a healthy gut microbiome. Foods high in fiber, plant-based proteins, prebiotic foods, limited added sugars, fermented foods will help support a healthy balance of gut bacteria. Healthy lifestyle choices like exercise and good-quality sleep also help with the diversity of the microbiome. These connections highlight how both modern biological research and Ayurvedic medicine promote a healthy gut microbiome.
Although Ayurveda and modern biology approach health from different perspectives, both emphasize the importance of maintaining balance within the body. Ayurveda focuses on restoring balance through individualized treatments, which include diet, herbal medicine, and healthy lifestyle habits, while modern biology explains these effects through concepts such as homeostasis, metabolism, and the microbiome. Although more scientific research is needed to better understand Ayurvedic practices, the core principles are consistent with modern recommendations for a healthy life. By integrating traditional knowledge with modern scientific understanding, researchers can gain better understanding on how to promote health and prevent disease.
