Ayurveda is generally thought of in terms of holistic medicine, but for the purpose of this paper, ayurveda is defined as the general concept that all parts of the body, mind, and consciousness are connected, and an imbalance in one will cause an imbalance in the other. There are many studies on ayurveda, and the general consensus seems to be positive. A lot of diseases seem to be caused by some imbalance in the body, mind, and possibly the consciousness, such as an overabundance or misplacement of a bacteria species in the body or an overexertion of the immune system wearing down on the body. These imbalances lead to other problems within the body, mind or consciousness. We’ve seen examples such as stress and diet having great impacts on the body, like heart disease or IBD. This generally reflects that the mind, body, and consciousness do have a connection and balance with each other.
Testing the concept of ayurveda directly could be a difficult task to take on, but there are many studies, and much to consider, in the simpler concept that imbalances in one part of the body can lead to imbalances and problems in other parts. Some examples of this would be the effects of diabetes on the body, and the many new connections that have been found between the body and the human microbiome.
In diabetes there is an imbalance in the insulin pathway. This imbalance can have effects on many different organs and body systems from the brain to the gut microbiome. A more immediate and obvious effect of imbalanced insulin levels are imbalanced blood sugar levels, often leading to hyperglycemia while the cells that need the glucose cannot uptake it and they starve. This can happen in type 1 from an overall decrease or absence of insulin production, or in type 2 from insulin resistance in the cell receptors. This immediate effect of hyperglycemia alone can lead to many problems, not only in the cardiac system itself, but effects have been seen as far reaching as depression and dental cavities.
Diabetes can be caused by many things. Type one diabetes could stem from hereditary factors, environmental factors, diseases or infections, drugs, and much more. Unfortunately in type 1 diabetes, a person may not know they have it until 25% or more of their islet cell mass (where insulin is made by beta cells) is gone. This is because there are no diabetes symptoms up until this point. Type 2 diabetes is less tricky and can be caused by hereditary factors, age, body weight, activity, high blood pressure, or high cholesterol.
The major effects that the imbalance of diabetes causes in the body present themselves in the eyes, kidneys, nervous system, brain, heart, and extremities. In the eyes, hyperglycemia and high blood pressure caused by diabetes can lead to retinopathy, cataracts, and glaucoma. In the kidneys those same conditions can cause damage and overwork resulting in nephropathy. In the nervous system hyperglycemia can cause peripheral nerve damage which can then lead to pain and numbness, which can further lead to undetected wounds, ending in infection and gangrene. For the brain, risk of stroke and cerebrovascular disease increase. In the heart, high blood pressure and insulin resistance increases the chance of coronary artery disease, and in the extremities, as mentioned before, gangrene and other complications become more likely due to nerve damage and reduced blood flow. On top of all of these connections in the body, there are also studies showing that diabetes has trends with aggression, depression, alcoholism, and unhappy marriages.
Recent studies have shown that the human microbiome is just as connected, if not more than, as our insulin pathway is to the rest of our body. The microbiome consists of all bacteria and other microorganisms living within and on the human body, although most studies mainly focus on bacteria within the GI tract. There is much we don’t know about the microbiome, but we are realizing how important it is with studies linking microbiome health with sleeping habits, weight and nutrition, the immune system, brain development, the cardiovascular system, and of course, the health of the GI tract.
How we first get our microbiome is yet to be discovered, but there is some evidence that it is already developing as early as fetal stages. There is further evidence to suggest the microbiome is enhanced and differentiated by birthing style and feeding style of infants, continuing to develop until the age of two or three. If the microbiome is altered in infancy or early childhood by something like antibiotics, there is some evidence, supported by the practice of administering antibiotic doses to livestock, that this can promote obesity (the goal of administering antibiotics to livestock), metabolic abnormalities, and autoimmune diseases.
According to NIH bacteria in the microbiome harvest energy from food, balance bacteria composition, manufacture neurotransmitters like serotonin (which affects sleep, mental well being, hunger, etc.), manufacture enzymes and vitamins (like vitamin K), and influence immune and metabolic functions in the body. Several other studies with mice also indicate these relationships and benefits, playing with a complete absence of a microbiome, antibiotics, probiotics, and stress tests to see effects on health, and try to pinpoint some of the signaling pathways between bacteria and brain.
There are proven links between parts of the body with each other, such as insulin imbalances with the nervous system, and the human microbiome with weight gain. As stated above, diabetes has many reaching effects on the body which can in turn increase the insulin imbalance that caused them. Stress on the body and mind is shown to present itself in gut behavior, which very likely includes the gut microbiome, and according to many of the studies, the microbiome can in turn affect the body. The signaling pathways of these phenomenons are mostly unknown, and just how great an effect parts of the body have on each other is also unknown, but future studies may very well increase our understanding of these relationships, and change the way we treat imbalances, disorders, and infections in the future.
