Early signs of starvation can be both physical and psychological as the body responds to an insufficient intake of calories and nutrients. Initially, an individual may experience persistent feelings of hunger and fatigue due to a lack of energy, as the body begins to deplete its glycogen stores. As starvation progresses, noticeable weight loss occurs along with muscle wasting as the body starts breaking down muscle tissue for energy. Physical symptoms can also include dizziness, lightheadedness, and fainting caused by low blood sugar levels.
Psychologically, a person may endure irritability, difficulty concentrating, and an overall decline in mental functioning. Starvation can also lead to a dramatic drop in energy levels, making even simple tasks exhausting. The skin may become dry and flaky, and hair may become thin and brittle due to deficiencies in essential vitamins and minerals. Swelling or edema, often noticeable in the ankles and feet, might occur due to a lack of protein. In severe cases, the immune system weakens significantly, increasing susceptibility to infections and diseases.
These signs serve as critical indicators that the body is not receiving adequate nutrition, and it is crucial to address these symptoms promptly to prevent long-term health consequences and potential organ damage.
