Annotation.
This article examines the role of carbohydrates in human health and analyzes
the physiological consequences of their deficiency and excess. It highlights that a lack of
carbohydrates can lead to energy deficiency, reduced nervous system activity, ketosis, and
other negative conditions. Furthermore, it substantiates the link between excessive
carbohydrate intake and diseases such as obesity, insulin resistance, and diabetes mellitus.
The article scientifically justifies the importance of moderate and balanced carbohydrate
consumption.
Key words:
carbohydrates, energy source, glucose, deficiency, excess, ketosis,
hypoglycemia, obesity, insulin, diabetes mellitus, metabolism, healthy nutrition, brain
function.
Main part:
Carbohydrates (carbs) are one of the main macronutrients necessary for human
life. They are used by cells as a source of energy and participate in all vital processes of the
div. Carbohydrates ingested through food are absorbed into the blood in the form of
glucose and delivered to all tissues. However, carbohydrates are not only useful in the div,
but their excess or deficiency can also lead to negative consequences. Therefore, this article
will extensively cover the effects of carbohydrate deficiency and excess on the human div.
When carbohydrates are not enough in the div, several important physiological processes
are disrupted. This condition occurs especially as a result of long-term dieting, starvation,
malnutrition, or the complete exclusion of carbohydrates from food. Energy deficiency:
Glucose is the main source of energy for cells in the div, and is especially necessary
for brain function. When carbohydrates are insufficient, a person feels constantly tired, weak,
and lethargic. Physical and mental activity decreases. Ketosis: When carbohydrates are
scarce, the div switches to using fat as its main source of energy. This leads to the
formation of ketone bodies. Ketosis can be beneficial if it is short-term, but if it lasts for a
long time, symptoms such as headache, nausea, and bad breath appear. Hypoglycemia:
Hypoglycemia occurs when blood glucose levels drop sharply. This condition can cause
dizziness, tremors, rapid heartbeat, and even fainting. Protein breakdown: When

carbohydrates are not enough, the div is forced to break down proteins for energy. This
leads to a decrease in muscle mass and worsens overall health. Excessive consumption of
carbohydrates is also harmful to the div. Negative conditions occur especially when simple
(fast-absorbing) carbohydrates are consumed in large quantities - sugar, white bread, sweet
drinks. Obesity: Excess carbohydrates are stored in the div as fat. In the long term, this
leads to obesity. Obesity increases the risk of cardiovascular disease, hormonal disorders,
and other diseases. Insulin resistance and type 2 diabetes:
Constantly high glucose levels reduce the div's sensitivity to insulin. This leads to
the development of type 2 diabetes. This condition is especially common in people with a
sedentary lifestyle. Cardiovascular diseases: Excess sugar and carbohydrates increase the
risks of heart disease, high cholesterol, and hypertension. Disruption of intestinal flora:
Excessive consumption of sugary products leads to a decrease in the number of beneficial
bacteria, which causes problems in the digestive system. Carbohydrates play an
indispensable role in human life. Their balance in the div plays an important role in
maintaining health. A carbohydrate deficiency can lead to conditions such as energy
deficiency, decreased brain function, ketosis, and hypoglycemia.
Conversely, an excess of carbohydrates increases the risk of obesity, diabetes, heart
disease, and metabolic syndrome. Therefore, consuming carbohydrates in moderation from
quality, wholesome sources is the foundation of a healthy lifestyle.
Effects of Carbohydrate Deficiency (Hypoglycemia)
Carbohydrate deficiency usually occurs in cases of insufficient food intake, severe
diets, improper intake of diabetic medications, or excessive physical exertion.
Main consequences:
Energy deficiency: Fatigue, muscle weakness, decreased performance.
Central nervous system disorders: Dizziness, tremors, fainting, decreased
concentration.
Hypoglycemic coma: In severe cases, fainting and a life-threatening condition.
Ketosis and acidosis: The div begins to break down fats as an alternative source of
energy, which leads to the accumulation of ketone bodies.
Immune deficiency: Against the background of energy deficiency, the immune
system weakens.
Effects of excess carbohydrates (hyperglycemia)
Excessive consumption of carbohydrates, especially simple (fast-digesting)
carbohydrates such as sugar, leads to a number of problems.
Main consequences
:
Overweight and obesity: Unnecessary excess energy is stored as fat.
Insulin resistance and type 2 diabetes: Persistently high glucose levels reduce insulin
sensitivity.

Metabolic syndrome: A condition characterized by arterial hypertension,
dyslipidemia, and obesity.
Inflammatory processes: Chronic hyperglycemia alters the immune response.
Candidiasis and infections: High glucose in the blood serves as a breeding ground for
microorganisms.
Tooth enamel erosion: Excessive consumption of simple sugars leads to caries.
Conclusion
: Carbohydrates are essential for the div, but it is important to consume
them in moderation. A deficiency can lead to energy deficiency and stunted growth, while
an excess can lead to obesity, diabetes, and cardiovascular disease. A healthy diet and
physical activity are key factors in preventing carbohydrate metabolism disorders.
Carbohydrates are the main source of energy for the human div. They are found in large
quantities in the daily diet and their amount directly affects the functioning of the div.
Deficiency or excess of carbohydrates can cause various physiological and pathological
conditions. This article analyzes the effects of carbohydrate deficiency and excess on the
human div.
