Our body 🧍♂️ needs glucose 🍬 to fuel metabolic processes ⚡, but too much of it 📈 in the blood 🩸 over a long period of time ⏳—a condition called hyperglycemia 📊—is the mark of diabetes mellitus 🩸. The body 🧍♂️ normally controls blood sugar levels 📊 with the hormone insulin 💉, which the pancreas 🫘 produces. In the disorder of diabetes 🩸, however, abnormal levels 📈 of glucose 🍬 accumulate in the blood 🩸 because the pancreas 🫘 does not produce sufficient insulin 💉.
Diabetes 🩸 is a prevalent illness 📊 around the world 🌍; it is among the most common chronic conditions ⏳ in the United States 🇺🇸, with over 10 million currently diagnosed cases 📈 and over 5 million people 👥 who are not aware 🤷 that they have the disorder 🩸. Prevalence rates 📊 for diagnosed diabetes 🩸 increase with age 📈 throughout the life span 👶👴, being many times higher 📈 among middle-aged 🧑 and elderly adults 👴 than among children 👶 and adolescents 👦.
Furthermore, this age difference ⚖️ is widening 📈—prevalence rates 📊 of diabetes 🩸 in the United States 🇺🇸 have increased fairly steadily 📈 for many years 📅 among middle-aged 🧑 and older people 👴, but not among younger individuals 👶.
The Types and Causes of Diabetes 🩸🔍
Diabetes 🩸 is not a single disease 🦠—it occurs in two major patterns 2️⃣ that require different kinds of treatment 💊 and may have somewhat different causes 🔍. The two forms 2️⃣ of diabetes are:
Type 1 Diabetes 1️⃣💉
Type 1 diabetes 1️⃣ (sometimes called insulin dependent diabetes mellitus) typically develops in childhood 👶 or adolescence 👦 and accounts for only 5 to 10% 📊 of diabetes cases. In this form of diabetes 🩸, autoimmune processes 🛡️ have destroyed cells 🧬 of the pancreas 🫘 that normally produce insulin 💉, and people afflicted with it require insulin injections 💉 to prevent acute ⚡ and very serious complications ⚠️.
An acute complication ⚠️ that occurs without insulin 💉❌ in type 1 diabetes 1️⃣ is called ketoacidosis 🧪, in which high levels 📈 of fatty acids 🧪 in the blood 🩸 lead to kidney malfunction 🫘 thereby causing wastes 🚫 to accumulate and poison ☠️ the body 🧍♂️. The symptoms of ketoacidosis 🧪 generally begin with chronic thirst 💧 and urination 💦, followed by an acute episode ⚡ of nausea 🤢, vomiting 🤮, abdominal pain 😣, and labored breathing 😮💨. About one-third 📊 of type 1 cases are diagnosed 📋 after these symptoms appear. If left untreated ❌, ketoacidosis 🧪 can lead to coma 😵 and death 💀 in a matter of days 📅 or weeks ⏰.
Type 2 Diabetes 2️⃣💊
Type 2 diabetes 2️⃣ (sometimes called non-insulin dependent diabetes mellitus) is very prevalent 📊, accounting for the vast majority 📈 of diabetes cases. In this form of diabetes 🩸, the pancreas 🫘 produces at least some insulin 💉, and treatment 💊 often does not require insulin injections 💉. Most, but not all ❌, people with type 2 diabetes 2️⃣ can manage their glucose levels 📊 by carefully following special diets 🥗 and taking medication 💊.
Although type 2 diabetes 2️⃣ can develop at any age 👶👴, it usually appears after the age of 40 4️⃣0️⃣. Most type 2 patients 📊 are very overweight 🍔, and many produce substantial amounts 📈 of insulin 💉—sometimes more than normal ➕—but their bodies 🧍♂️ seem to resist the glucose-controlling action 🎮 of insulin 💉. Normal-weight type 2 patients 📊 seem to produce reduced levels 📉 of insulin 💉. In either case, hyperglycemia 📈 results.
What Causes the Pancreas to Reduce Its Production of Insulin? 🫘❓
Although the causes are not well understood 🤔, twin studies 👥 have demonstrated that genetic factors 🧬 are involved in both type 1 1️⃣ and type 2 2️⃣ diabetes. Most diabetics 🩸 probably inherit some form of susceptibility 🧬 to the effects of environmental conditions 🌍 that could affect insulin production 💉. In type 1 1️⃣, one environmental condition 🌍 seems to involve a viral infection 🦠 that stimulates the immune system 🛡️ to attack pancreas cells 🫘.
For type 2 2️⃣, evidence exists for three possible conditions 3️⃣: diets high in fat 🍔 and sugar 🍭, stress 😰, and an overproduction 📈 of a protein 🧬 that impairs the metabolism of sugars 🍬 and carbohydrates 🍞. At this time ⏰, however, the nature of people's susceptibility 🧬 to diabetes 🩸 and the environmental conditions 🌍 involved are not clear ❓.
Health Implications of Diabetes ⚠️🩸
Diabetes 🩸 can be a direct cause of death 💀; in the United States 🇺🇸 it claims over 60,000 lives 📊 each year 📅. Many of these deaths 💀 result from acute complications ⚡ that can be prevented 🛡️ by appropriate medical care 🏥. Few diabetics 🩸 die of acute complications ⚡ if they follow the recommended medical regimens 💊 for controlling glucose levels 📊.
But the deaths 💀 that are caused directly by diabetes 🩸 constitute only part of the serious health effects ⚠️ of this disease 🦠. Diabetes 🩸 is implicated in the development of a variety of disabling health problems ♿ and contributes indirectly to about 100,000 deaths 💀 each year 📅. One health problem 🏥 diabetes can lead to is neuropathy 🧠 or nerve disease. High blood glucose levels 📈 appear to cause chemical reactions 🧪 that can destroy the myelin sheath 🧬 that insulates nerve fibers 🧠. When this occurs in peripheral fibers 🦴, such as in the feet 🦶, the person may lose sensation ❌👐 in the affected area or have abnormal sensations 😣, such as chronic pain 🤕. If the damage occurs in autonomic nerves 🧠, the symptoms may include chronic dizziness 😵, urinary incontinence 💦, and sexual impotence 🚫 (in males ♂️).
Serious Health Problems from Diabetes ⚠️📊
Diabetes 🩸 can also lead to the development of other serious health problems 🏥. Physicians 👨⚕️ Charles Kilo and Joseph Williamson (1987) have noted that compared to individuals who are not diabetic ✅, people who have diabetes 🩸 are:
- 6.8 times more likely 📈 to become blind 👁️❌
- 11.3 times more likely 📈 to develop kidney disease 🫘
- 29.9 times more likely 📈 to get gangrene 🦶❌
- 4.6 times more likely 📈 to develop heart disease ❤️
- 5.4 times more likely 📈 to have a stroke 🧠
The way diabetes 🩸 contributes to these health problems 🏥 is through its effects on the vascular system 🩸. High levels 📈 of glucose 🍬 in the blood 🩸 lead to a thickening 🧱 of arterial walls 🩸 as a result of atherosclerosis 🫀. This can occur in large blood vessels 🩸, such as those in the legs 🦵 and near the head 🧠, causing gangrene 🦶 in a limb or heart disease ❤️. It can also occur in small blood vessels 🩸 and capillaries 🧬 such as those in the eyes 👁️, kidneys 🫘, and brain 🧠. Eye disease 👁️ that results from diabetes 🩸 can be treated effectively ✅ if caught early 🏁.
The long-term health risks ⚠️ of diabetes 🩸 are extremely serious 😱, and patients 🤒 and their families 👨👩👧👦 worry 😟 about them greatly 📈. They worry 😰 about the possibilities of, for instance, dying prematurely 💀, becoming blind 👁️❌, losing a limb 🦵 if gangrene cannot be controlled 🎮, and being unable ❌ to perform sexually 🚫.
Medical Regimens for Diabetes 💊🩸
Ideally 🎯, the treatment for diabetes 🩸 would enable the body 🧍♂️ to perform or simulate the normal biochemical activities ⚡ for processing and maintaining normal levels 📊 of glucose 🍬. Medical regimens 💊 available today 📅 compensate for these differences 🔄, but they do not enable the body 🧍♂️ to function exactly as it normally does ❌, such as in continuously monitoring 📊 the need for insulin 💉 and secreting this hormone 🧪 in precisely needed bursts ⚡. Physicians 👨⚕️ generally prescribe somewhat different regimens 💊 for type 1 1️⃣ and type 2 2️⃣ patients and tailor the treatment 🎯 for individual needs 👤.
The main approach 🎯 for treating diabetes 🩸 entails a balancing act ⚖️ with medication 💊, diet 🥗, and regular exercise 🏃♀️ under medical supervision 👨⚕️. Can diabetics 🩸 reduce their long-term risks ⚠️ by keeping their blood glucose levels 📊 within the normal range ✅? Yes ✅, these risks can be markedly reduced 📉—with complications ⚠️ occurring much later ⏰ and far less often 📉—if diabetics 🩸 receive intensive medical care 🏥 and control their blood glucose levels 📊 by carefully following prescribed treatment regimens 💊.
But the full extent 📊 of the reduced risk 📉 is unclear ❓ because long-term complications ⏳ of diabetes 🩸 take many years 📅 or decades 📆 to develop, and many diabetics 🩸 with good blood glucose control 🎮 are not always able ❌ to keep their glucose levels 📊 consistently in the normal range ✅. Regimens 💊 for treating diabetes 🩸 today 📅 allow patients to have better control 🎮 over their blood sugar 🍬 than in the past ⏮️, but these new methods 💡 are still not perfect ❌. And many diabetics 🩸 who have regimens 💊 that could provide good control 🎮 over their blood glucose 🍬 do not adhere to them closely ❌.
Do Diabetics Adhere to Their Regimens? 🤔💊
Noncompliance 🚫 with the treatment regimen 💊 is a major problem 😔 in managing diabetes 🩸. According to researchers 👨🔬 who have reviewed studies 📊 on this issue, the most thorough survey 📋 of patients' adherence 📊 to diabetes regimens 💊 found that:
- 58% 📊 administered the wrong dose 💉❌ of insulin.
- 77% 📊 tested their glucose levels 🩸 incorrectly ❌ or interpreted the results 📊 in a manner likely to be detrimental ⚠️ to their treatment 💊.
- 75% 📊 did not eat 🍽️ the prescribed foods 🥗.
- 75% 📊 did not eat 🍽️ with sufficient regularity ⏰.
People with diabetes 🩸 generally do try ✅ to adhere to their regimens 💊, but they do not always succeed ❌. One reason some fail 📉 may be that they rely on symptoms they perceive 👀, such as dizziness 😵 or emotional states 😢, to assess their glucose levels 📊. Although many diabetics 🩸 can make crude estimates 🤔 of their actual glucose levels 📊 on the basis of perceived symptoms 👀, these judgments are usually not very accurate ❌.
Research 🔬 with type 1 diabetics 1️⃣, ranging from about 12 years of age 1️⃣2️⃣ to old age 👴, found that they have more difficulty 😔 following dietary 🥗 and exercise advice 🏃♀️ than the more "medical" aspects 💊 of their regimens (testing their glucose levels 🩸 and taking their insulin 💉 on time ⏰).
The patients' self-reports 📝 indicated they had complied fairly closely ✅ with their insulin 💉 and testing regimens 🩸. However, self-report data 📋 can be misleading ⚠️.
Psychosocial Factors in Diabetes Care 🧠🩸
Compliance ✅ to medical recommendations 💊 tends to be low 📉 when the regimen is complex 🧩, must be followed for a long time ⏳, requires changes 🔄 in the person's lifestyle 🏡, and is designed to prevent 🛡️ rather than cure 💊 illness. Treatment regimens 💊 for diabetes 🩸 have all of these characteristics ✅. In addition, psychosocial factors 🧠 in patients' lives are related to compliance ✅. Two of these factors 2️⃣ are social support 👥 and self-efficacy 💪.
A study 🔬 of type 2 diabetics 2️⃣ found that their self-reports 📝 of adherence ✅ to dietary 🥗, exercise 🏃♀️ and glucose testing 🩸 aspects of their regimens increased 📈 with their perceived social support 👥. Coping processes 💪 are also important 🎯 in diabetes care 🩸. Stress 😰 impairs blood sugar control 📊 in many diabetics 🩸, especially those who have sedentary lifestyles 🛋️.
How Stress Affects Diabetes 😰🩸
The effects of stress 😰 may occur in two ways 2️⃣. First 1️⃣, when people are under stress 😰, the adrenal glands 🫘 release epinephrine ⚡ and cortisol 🧪 into the bloodstream 🩸. Epinephrine ⚡ causes the pancreas 🫘 to decrease insulin production 💉📉. Second 2️⃣, cortisol 🧪 causes the liver 🫘 to increase glucose production 🍬📈, and body 🧍♂️ thus decreases its use 📉 of glucose 🍬. These biochemical actions 🧪 to stress 😰 clearly worsen 📈 the glucose regulation problems 📊 of diabetics 🩸.
Everyday Challenges in Diabetes Management 📅🤔
People's everyday lives 📅 present many circumstances 🔄 that make it difficult 😔 to adhere to diabetes regimens 💊. Diabetics 🩸 may feel that testing their glucose levels 🩸 at work 💼 or school 🎓 is embarrassing 😳, or forget ❌ to take their testing materials 🧪 with them, or have difficulty 😔 getting up weekend mornings 🌅 to take their injections 💉 on time ⏰, or make mistakes ❌ in judgments 🤔 about what they can eat 🍽️, for example.
One other psychosocial situation 🧠 that can lead to noncompliance 🚫 is when the patient 🤒 and the physician 👨⚕️ have different goals 🎯 of treatment. The main focus 🎯 of doctors 👨⚕️ is on preventing long-term complications ⏳ from developing. In comparison, patients 🤒 seem to be more interested 🎯 in preventing hypoglycemic episodes 📉 and in promoting their day-to-day well-being 😊 and activity 🏃♀️. Not surprisingly, the patients' actual glucose levels 📊 more closely match the goals 🎯 of their choice than those of physicians 👨⚕️.
Summary 📋
Diabetes 🩸 is a complex chronic condition ⏳ that requires careful management 💊 through medication 💉, diet 🥗, and exercise 🏃♀️. The two main types 2️⃣—Type 1 1️⃣ and Type 2 2️⃣—differ in their causes 🔍 and treatments 💊, but both carry serious long-term health risks ⚠️ including blindness 👁️❌, kidney disease 🫘, heart disease ❤️, and stroke 🧠. Adherence to treatment regimens 💊 remains a significant challenge 😔, influenced by psychosocial factors 🧠 such as social support 👥, self-efficacy 💪, stress 😰, and the complexity 🧩 of daily management 📅. Understanding these factors is crucial 🎯 for effective diabetes care 🏥 and improving quality of life ✨ for patients and their families 👨👩👧👦.
