Symptom family: Body Weight Issues
Sub-symptom(s): Abdominal Fat
Obesity is a medical condition characterized by an excess accumulation of body fat to the extent that it may have a negative impact on health. It is typically defined using the body mass index (BMI), where a BMI of 30 or above is classified as obese.
Obesity is more than just an issue of physical appearance; it is associated with various health risks, including heart disease, diabetes, and high blood pressure. It encompasses various forms of weight gain, including abdominal fat, and is a growing health concern worldwide.
Traditional Chinese Medicine (TCM) approaches obesity as a complex condition resulting from imbalances within the body. Unlike Western medicine, which often focuses on calorie intake and physical activity, TCM considers obesity a manifestation of disharmony in the body's natural energy flow or Qi.
TCM identifies different patterns of disharmony causing obesity and emphasizes the importance of individualized treatment to restore balance. This holistic approach encompasses diet, lifestyle, herbal remedies, and acupuncture.
In TCM, obesity is commonly associated with the accumulation of Damp-Phlegm and Qi Deficiency. The Damp-Phlegm pattern, often seen in obesity, is characterized by symptoms like profuse white sputum, feeling of chest oppression, nausea, and swollen limbs. This pattern indicates an imbalance where the body improperly metabolizes fluids and fats.
Another significant pattern is Spleen Qi Deficiency, manifesting as poor appetite control, abdominal distension, fatigue, and weakness. Addressing these underlying imbalances is key to TCM treatment, as it goes beyond mere weight loss to improving overall health and vitality.
Explore below more details about what might cause Obesity according to TCM.
In TCM "Phlegm" as a pattern of disharmony is a complex concept that extends beyond the physical manifestation of mucus. It represents a pathological factor that can disrupt the flow of Qi (vital energy) and blood, leading to various health issues. Phlegm in TCM is seen as a sticky, turbid substance arising from the body's inability to metabolize fluids properly, often due to a dysfunction of the spleen. It's not only associated with respiratory problems like cough and congestion but also with systemic issues. Symptoms can include a feeling of heaviness, mental cloudiness, dizziness, and in some cases, the formation of lumps or masses. Phlegm can even be "invisible," contributing to emotional disturbances like depression or stress. ... see more

Qi Deficiency in TCM is like running low on battery power. Qi is the vital energy that powers every function in your body. When there's a Qi Deficiency, it means your body doesn't have enough of this essential energy. This can make you feel tired all the time, weak, or even cause shortness of breath. It's similar to how you feel when you haven't had enough sleep or nutritious food. Your body just doesn't have the energy it needs to perform at its best. Unlike modern medicine, which often focuses on specific physical causes for fatigue and weakness, TCM views Qi Deficiency as an overall energy depletion that affects your entire well-being, and it seeks to replenish and balance this vital energy.... see more

"Dampness" in TCM is a concept that describes a pattern of disharmony where the body accumulates excess moisture. Imagine the heavy, sticky feeling you get on a very humid day; that's similar to what dampness feels like internally. It can manifest as a sense of heaviness, bloating, sluggishness, or even a foggy mind. This condition is often thought to arise from environmental factors like living in a damp place, dietary habits that promote moisture in the body, or internal imbalances that hinder the body's ability to process fluids properly. In TCM, dampness can obstruct the normal flow of energy and fluids in the body, leading to various symptoms.... see more

Qi Sinking is a pattern of disharmony in TCM where the body's energy, or Qi, is thought to "sink" or drop down. Imagine a balloon slowly deflating and falling; that's similar to what happens with Qi Sinking. This can lead to feelings of heaviness, fatigue, and even physical symptoms like prolapse of organs or frequent urination. It's as if the body's energy, which usually supports and holds things in place, isn't able to do its job properly. TCM views this as an imbalance where the uplifting and supporting qualities of Qi are weakened.... see more

In TCM the Spleen plays a vital role in digestion and transformation, converting food into energy and nutrients, and overseeing the distribution of Qi and Blood. It's also crucial in maintaining the health of muscles and limbs and ensuring the blood remains within the vessels. When the Spleen malfunctions in TCM, it can lead to a variety of issues such as digestive disorders, fatigue, weak muscles, bloating, and a feeling of heaviness. It can also cause a pale complexion, poor appetite, and a tendency to bruise easily. Emotionally, a Spleen imbalance is often associated with excessive worry or overthinking, reflecting its role in the interplay between physical and mental health.... see more

In TCM the Uterus (or "Bao Gong") is not just a reproductive organ but a vital system closely linked to Kidney energy, responsible for menstrual health, fertility, and pregnancy. It's also connected to the Heart and Liver, reflecting the importance of emotional and blood health in reproductive wellness. In TCM, the Uterus is seen as a reservoir of Blood and Qi, crucial for reproductive health and general vitality. When the Uterus malfunctions or is imbalanced, it can lead to menstrual irregularities, infertility, miscarriages, or menopausal symptoms. Additionally, there might be symptoms like lower abdominal pain or emotional disturbances such as mood swings, often linked to Liver Qi stagnation. These manifestations highlight the TCM perspective that the health of the Uterus is intertwined with the overall balance of energy and blood in the body, as well as emotional well-being.... see more

In TCM the Lungs are seen as the organ responsible for controlling Qi and respiration, as well as being a key part of the body's defensive system. They are thought to maintain the balance and flow of air and moisture, and are closely linked to the skin and hair. When the Lungs are imbalanced or malfunctioning in TCM, it can lead to respiratory issues like coughing or asthma, a weakened immune system, dry skin, and emotional disturbances such as sadness or grief. These symptoms are believed to arise from disruptions in the Lungs' ability to regulate Qi and protect the body, highlighting their central role in maintaining overall health and well-being.... see more
