What is the main consequence of the beriberi condition?

The main consequence of beriberi is indeed neuropathy and fatigue, which stem from a deficiency of thiamine (vitamin B1). Thiamine is crucial for energy metabolism and the proper functioning of the nervous system. When there is a lack of this vitamin, it can lead to severe neurological symptoms, including peripheral neuropathy, which manifests as weakness, tingling, or numbness in the limbs. Additionally, individuals may experience significant fatigue due to the impaired energy production in the body, leading to a general decrease in stamina and well-being.

This condition primarily affects the neurological system, hence the focus on neuropathy and fatigue as key consequences. Other options, while related to health issues, do not specifically capture the primary effects associated with a thiamine deficiency that characterizes beriberi.
