Symptoms of scurvy

Until the beginning of the 20th century, scurvy was considered a deadly disease. During the first round-the-world expedition of Vasco Da Gamma, more than one hundred sailors died as a result of this disease (almost a third of all participants). According to current estimates, over a million seamen died from scurvy over the entire period of exploration of the sea space. Only in 1932 was it established that the cause of this disease is a lack of vitamin C (ascorbic acid) in the body. Studies have confirmed that this vitamin plays an important role in biochemical processes, including the formation of the main element of the connective tissue - collagen.
As a result of research, it turned out that vitamin C cannot be synthesized in the body. A person receives this substance only from the consumed food. With the complete cessation of intake of vitamin C with food, scurvy develops in 1-3 months. First, a person appears lethargy, exhaustion, fatigue, his gums are made loose, ulcers form on them, his teeth begin to lurch and fall out.Subsequently, because of the constant hemorrhages, pains in the muscles appear, subcutaneous hematomas are formed. A person falls into a state of apathy and depression, eventually his kidneys and lungs fail. As a rule, scurvy lasts from several weeks to several months.

Why scurvy appears

Similar symptoms in patients with scurvy are due to the participation of vitamin C in a number of very important biochemical processes: ascorbic acid ensures the penetration of glucose into the cells of organs and tissues. Without glucose, a person develops a breakdown and exhaustion. Vitamin C is involved in the synthesis of collagen (connective tissue). Without collagen, the gums are loosened, the teeth fall out, the walls of blood vessels become brittle, hematomas and bleeding appear. Without vitamin C, synthesis of serotonin (the pleasure hormone) is impossible, as a result, a person develops depression and apathy. This vitamin is required for normal functioning of the intestinal microflora, in its absence a person develops dysbacteriosis, the absorption of nutrients and the synthesis of other vitamins are impaired. This leads to chronic diarrhea and further exhaustion.
As a result of the violation of these biochemical processes, other processes in the body also change. In humans, immunity decreases, anemia develops. In scurvy, the cause of death is most often a hemorrhage into vital organs (kidney, lung) or heart failure.
