Mitochondrial complex V deficiency is a shortage (deficiency) of a protein complex called complex V or a loss of its function. Complex V is found in cell structures called mitochondria, which convert the energy from food into a form that cells can use. Complex V is the last of five mitochondrial complexes that carry out a multistep process called oxidative phosphorylation, through which cells derive much of their energy.
Descrição
Mitochondrial complex V deficiency is a shortage (deficiency) of a protein complex called complex V or a loss of its function. Complex V is found in cell structures called mitochondria, which convert the energy from food into a form that cells can use. Complex V is the last of five mitochondrial complexes that carry out a multistep process called oxidative phosphorylation, through which cells derive much of their energy.
Mitochondrial complex V deficiency can cause a wide variety of signs and symptoms affecting many organs and systems of the body, particularly the nervous system and the heart. The disorder can be life-threatening in infancy or early childhood. Affected individuals may have feeding problems, slow growth, low muscle tone (hypotonia), extreme fatigue (lethargy), and developmental delay. They tend to develop elevated levels of lactic acid in the blood (lactic acidosis), which can cause nausea, vomiting, weakness, and rapid breathing. High levels of ammonia in the blood (hyperammonemia) can also occur in affected individuals, and in some cases result in abnormal brain function (encephalopathy) and damage to other organs.
Another common feature of mitochondrial complex V deficiency is hypertrophic cardiomyopathy. This condition is characterised by thickening (hypertrophy) of the heart (cardiac) muscle that can lead to heart failure. People with mitochondrial complex V deficiency may also have a characteristic pattern of facial features, including a high forehead, curved eyebrows, outside corners of the eyes that point downward (downslanting palpebral fissures), a prominent bridge of the nose, low-set ears, thin lips, and a small chin (micrognathia).
Some people with mitochondrial complex V deficiency have groups of signs and symptoms that are classified as a specific syndrome. For example, mitochondrial complex V deficiency can cause a condition called neuropathy, ataxia, and retinitis pigmentosa (NARP). NARP causes a variety of signs and symptoms chiefly affecting the nervous system. Beginning in childhood or early adulthood, most people with NARP experience numbness, tingling, or pain in the arms and legs (sensory neuropathy); muscle weakness; and problems with balance and coordination (ataxia). Many affected individuals also have cognitive impairment and an eye disorder called retinitis pigmentosa that causes vision loss.
A condition called Leigh syndrome can also be caused by mitochondrial complex V deficiency. Leigh syndrome is characterised by progressive loss of mental and movement abilities (developmental or psychomotor regression) and typically results in death within 2 to 3 years after the onset of symptoms. Both NARP and Leigh syndrome can also have other causes.

Má absorção gastrointestinal
Gastrointestinal malabsorption syndrome means a failure to fully absorb digested foods from the gut (bowel) into your body. There are many different causes. Prolonged intestinal malabsorption may cause problems because of a lack of carbohydrates, proteins, fats, minerals and vitamins that are essential to keep you healthy. The treatment will.

Anemia
Anemia means that you have fewer red blood cells than normal or you have less haemoglobin than normal in each red blood cell. In either case, a reduced amount of oxygen is carried around in the bloodstream. Anaemia types and causes Iron-deficiency anaemia Lack of iron is the most common type of anaemia in the UK. This is called iron-deficiency.

Baixo nível de testosterona
Low testosterone in men (testosterone deficiency) is often part of the ageing process and therefore common in older men. It can also occur at any age as a result of conditions affecting the testicles or the pituitary gland in the brain. Low testosterone can be treated with testosterone replacement therapy. Any underlying cause for the testosterone.

Posso tomar complexo de Vitamina B e Vitamina C juntos?
There is no harmful interaction between Vitamin B complex and Vitamin C. In fact, these water-soluble vitamins are often found together in the same supplement (such as Berocca or multivitamin tablets) because they work well together to support energy levels and the immune system. Why this happens Both Vitamin B complex and Vitamin C are.
