The way the factors like heat, alcohol and medication have affected the couple’s cardiovascular systems, nervous systems, kidneys and endocrine systems has been dealt with in order to shed light on the reason behind the deaths. The way the different factors interact with each other and impact the human physiology, has been used to find out the cause of death.
After considering the different evidences and the medical reports, it can be understood that the alcohol, the hot water and the lasix are the three probable elements that have caused the deaths. Now, the only things common about these three elements are their influences on the human physiology. Furosemide or lasix is a loop diuretic used for treating heart issues, excess tension and other issues. Along with many other diuretics, furosemide is included in the list of banned substances of the World Anti-Doping Agency, because it can mask the presence of other substances in the body. Like other loop diuretics, furosemide deals with exchanging of ions. It reduces the water content of the body. These tallies with the maid’s observation that Mr. Underhill used to complain that he needed to use the bathroom frequently since his last visit to the GP. This drug results in lowering of blood pressure and dehydration. Hot water leads to the temperature of the body getting increased beyond the normal. The human body has a homeostatic system that helps it adapt to the changes in temperature. For example, if the temperature increases, the blood pressure decreases in order to make adjustments. Similarly, blood pressure increases with fall in temperature.
已热，酒精和药物等因素都影响了夫妻双方的心血管系统，神经系统，肾脏和内分泌系统的方式处理，以揭示背后的原因的死亡。已被用于不同的因素相互作用，彼此影响人体生理，找出死因。
考虑不同的证据，医疗报告后，它可以被理解的是，醇，热水和速尿三个可能的元素，因而死亡。现在，这三个要素共同的唯一的东西是对人体生理的影响。速尿或袢利尿剂速尿是一种用于治疗心脏问题，张力过大等问题。随着许多其他利尿剂，速尿被列入世界反兴奋剂机构禁用物质清单中的，因为它可能会掩盖其他物质在体内的存在。像其他袢利尿剂，速尿离子交换处理。它降低体内的水含量。这些相吻合，昂德希尔先生与女佣的观察，曾经抱怨说，他需要经常使用的浴室，因为他上次访问的GP。这种药物的查询结果，降低血压和脱水。热水导致温度得到增加超出了正常的身体。人体具有自我平衡的系统，帮助它适应温度的变化。例如，如果温度的增加，血压降低，以便进行调整。同样，血压随温度的下降而增加。
