The finer-size sand and clay which fill the spaces between the larger clasts is often deposited later on top of the large clasts and then sifts down between them to fill the interstitial spaces. The deposition of a chemical cement then binds the sediment into a rock. Conglomerate has very few commercial uses.
The brain is particularly sensitive to changes in the sodium level in blood. Therefore, symptoms of brain dysfunction, such as sluggishness (lethargy) and confusion, occur first. If the sodium level in blood falls quickly, symptoms tend to develop rapidly and be more severe.
Seek immediate medical attention if you have any of these unlikely but serious symptoms of a low level of sodium in the blood: loss of appetite, severe nausea, vomiting, severe headache, muscle weakness/spasms/cramps, sudden weight gain, unusual tiredness, unusual severe drowsiness, mental/mood changes (such as confusion, hallucinations, irritability), loss of consciousness, seizures, slow/shallow breathing.
