Abstract
Diabetes Mellitus is a metabolic disorder that is caused by reduced insulin secretion or insulin resistance. It is of three types but the most common form is
Type 2 Diabetes Mellitus (T2DM). The prevalence of T2DM was estimated 285 million in 2009 by The International Diabetes Federation (IDF), which increased
at an alarming rate of 536.6 million in 2021. This review article focused on the researches being done on diabetes complications and the self-management
practices used to control them. The studies and government reports that show data on the role of self management practices in preventing the ill eff ects of
diabetes were included. Intervention-based studies were excluded. The data was collected from recent researches through several search engines. Indian
data on diabetes have been extracted through National Family Health Survey-05 (NFHS-05). The most prevalent complications were found to be acute
(hypoglycemia and hyperglycemia) and chronic macro-vascular (heart attack and stroke) and micro-vascular (retinopathy, nephropathy and neuropathy).
According to The American Association of Diabetes Educators (AADE), seven self-care behaviours, namely healthy eating, being active, monitoring, taking
medicines, problem-solving, healthy coping and reducing risks are key indicators of good glycemic control and preventing diabetes complications. Also,
patient-oriented diabetes self-management education (DSME) was found to be equally eff ective. These education programs must target to raise the way
of living of diabetic people through healthy eating practices and physical activities; managing body weight, HbA1c and lipid levels; understanding diabetes,
keeping track of glucose levels and knowing the importance of compliance with medication; emotional encouragement and terminating the use of alcohol and
tobacco.

Introduction
Diabetes Mellitus is a metabolic disorder indicated by poor
metabolism of macronutrients namely carbohydrates, proteins and
fats. It is an outcome of reduced insulin secretion, insulin resistance
or collaboration of both the factors. It is categorized into three main
types: Type 1 Diabetes Mellitus (T1DM), Type 2 Diabetes Mellitus
(T2DM) and Gestational Diabetes and the most common form
is T2DM as it can be seen in more than 90% of all diabetes cases worldwide [1]. The rate of T2DM cases has been increasing at an
alarming rate in recent decades [2-5]. The major reason behind this
outbreak is urbanization and changing lifestyle of people, adopting
the sedentary mode of living [6].
Prevalence of Type 2 Diabetes Mellitus:
The International Diabetes Federation (IDF) evaluated the
worldwide prevalence of T2DM and found that the total count was
285 million in 2009 [7], 366 million in 2011 [8], 382 million in 2013
[9], 415 million in 2015 [10], 425 million in 2017 [11], 463 million
in 2019 [12], and 536.6 million in 2021 [13]. The National Family
Health Survey (NFHS-5) report of 2019-21 revealed the total sum of
diabetic people in both urban and rural areas in India. It concluded
that 6.1% adult women and 7.3% adult men have blood sugar level
of 141-160 mg/dl (high). Likewise, 6.3% women and 7.2% men were at blood sugar level of >160 mg/dl (very high) and 13.5% women and
15.6% men were those who took medicines to control their blood
sugar level [14].This literature review has been done on related studies by
different researchers across the world. It comprises the findings of
researchers and their viewpoint on diabetes complications and their
treatment. Those studies and government reports were included
which show data on the prevalence rate of T2DM and the role of
self management practices in preventing the ill effects of diabetes.
Those studies were excluded from the current review which were
intervention-based. The data was collected from recent researches
through Google Scholar, PMC, Science Direct Elsevier and a well known
Scopus indexed journal ‘Diabetes Care’. The IDF records
have also been used. American Diabetes Association (ADA) position
statements were taken into consideration while searching the data.
Indian data like the prevalence rate of diabetes have been extracted
through the latest survey by NFHS (NFHS-05). Supplementary data
were collected through the Google search engine. Certain keywords
were used to make the search easier, such as: Type 2 diabetes mellitus,
macro-vascular complications of diabetes, diabetes retinopathy,
stroke in T2DM, management of hyperglycemia in type 2 diabetes, self
management of diabetes, self management in diabetes complications,
acute complications of type 2 diabetes and so forth.
Type 2 Diabetes Complications:
When it comes to the diagnosis of T2DM, many times aberrant
symptoms make it difficult to self-evaluate T2DM. Thus, while
medical prognosis, some patients remain asymptomatic while others
came with alarming hyperglycemia or even diabetes ketoacidosis
[15]. The management of T2DM becomes a complex process through
several patho-physiological defects [1,16] and ‘ABCDE’ of diabetes
management, comprises of Age, Body weight, Complications,
Duration of disease, Education, expense and etiology [17]. It is a
persistent disorder that demands full-time medical support, self supervision
for deviated blood glucose levels, lipid profile and blood
pressure. These factors will assist in intercepting acute (hypoglycemia
and hyperglycemia) as well as chronic macro-vascular (heart attack
and stroke) and micro-vascular (retinopathy, nephropathy and
neuropathy) complications [17-19]. The data on rising cases of
diabetes complications in the young adult population residing not
only in underserved communities, making it difficult to work for its
prevention [20].In people with T2DM, there is a positive relationship between
severe hypoglycaemia and rising death rate [21-22]. Hypoglycemia,
when uncontrolled, may lead to perplexity, seizure, coma [23],
treatment-related shakiness, excessive fatigue, ravenousness, reduced
muscle strength and headache. Also, the recurrence and intensity
of hypoglycemic episodes have a great effect on life quality of the
patients [24].
Atherosclerotic Cardiovascular Disease (ASCVD), commonly
known as Coronary Heart Disease (CHD) is the foremost cause of
death in diabetic patients. The patients with CHD and diabetes pay
higher medical expenditures i.e., approximately $37.3 billion for
seeking cardiovascular-related care [25]. Heart failure is another big reason for death among diabetic patients. Data from recent studies
showed that the heart failure cases were twice in diabetic patients than
in non-diabetic patients [26-27]. To prevent and manage the risk
of ASCVD and heart failure effectively, diabetic patients must have
their routine check-ups for cardiovascular disease (CVD) risk factors
at least once a year. These risk factors may be obesity, hypertension,
dyslipidemia, smoking, family history of premature CHD, chronic
kidney disease (CKD) and presence of albuminuria [28]. It is evident
that the treatment of heart diseases in association with hypertension,
hyperglycemia, dyslipidemia and microalbuminuria may reduce
the risk of both macro-vascular and micro-vascular complications
of T2DM [29]. High blood pressure is a vital consequence for both
ASCVD and micro-vascular complications and many studies proved
that antihypertensive therapy decrease ASCVD chances, heart failure
and micro-vascular complications [30]. Also, randomized controlled
trials (RCT) have exhibited that diabetic patients should be treated to
reach the target of less than 140/90 mmHg [28]. T2DM can lead to
stroke and thus becomes a major reason behind the deaths of diabetic
patients [31-33]. Cardio-metabolic agents like excessive body weight,
high blood pressure and deviated lipid levels in the body are usually
accompanied with T2DM and lead to higher chances of suffering
from stroke as compared to the non-diabetic population [32,34-36].
Diabetic retinopathy is a tremendously particular micro-vascular
complication in diabetes which largely depends on the duration
of diabetes and the extent of glycemic control [37]. It is the most
commonly occurring eye disorder, comprising of various forms
such as glaucoma and cataract in people with diabetes (aged 20-74)
residing in developing nations [28]. It is found to be the foremost
reason of preventable blindness among working-aged (20-74 years)
diabetic people in many countries [38]. Because of T2DM, patients
may also suffer from CKD which is thus known as diabetic kidney
disease or diabetic nephropathy and is likely to occur in 20-40%
of T2DM patients [39-42]. A variety of clinical trials analyzed
that glycemic control has a direct effect on the prevention of CKD
and its advancement. The outcome of glucose-lowering therapies
on CKD could help elucidate glycated haemoglobin targets [28].
Diabetic neuropathy is nerve dysfunctionality that occurs in patients
with uncontrolled diabetes mellitus and categorizes as peripheral,
autonomic, proximal and focal. Because of irregular dispersal of
pressure, diabetic foot ulcers may evolve. The timely diagnosis
of diabetic neuropathy helps in a lesser cost of hospital stay and
lesser chances of lower-limb amputations. The probability of
getting suffered from all these complications may be decreased at a
remarkable level by a controlled blood glucose level, early diagnosis,
screening and treatment, and providing proper diabetes management
education [43].
Self-Management in Type 2 Diabetes Mellitus:
Self-management can be understood as the process of dynamic
involvement of patients in their long-term treatment of disease
[44]. The American Association of Diabetes Educators (AADE)
elucidates AADE7 Self-Care Behaviours (healthy eating, being active,
monitoring, taking medicines, problem-solving, healthy coping and
reducing risks) as a foundation for patient-oriented diabetes self management
education (DSME) and care [45]. DSME is a way to incorporate the understanding and ability for self-care. The agenda
of this process is to reinforce decision-making, self-care practices,
coping strategies and coordination with the health professionals to
heighten the standard of living [46]. These education programs must
target to raise the way of living of diabetic people through healthy
eating practices and physical activities; managing body weight, HbA1c
and lipid levels; understanding diabetes, keeping track of glucose
levels and knowing the importance of compliance with medication;
emotional encouragement and terminating the use of alcohol and
tobacco [47]. The complications of T2DM aggravate the patient’s
health consequences, therapeutic options, the constant need for care
and expenses linked with treatment of the disease [48]. The health
personnel, policy makers and the patients together are aiming at
upgrading the self-management practices, involving attaining good
control on blood sugar and lipid levels, optimizing blood pressure
to minimize the risk factors for health consequences due to T2DM
[49]. The recommendations dispersed by the collaborated research of
International Diabetes Federation and American Diabetes Association
revealed the importance of monitoring blood glucose levels in the
process of managing diabetes consequences [50].Mumu et al conducted research on 374 T2DM patients and
proclaimed that adhering to significant changes in way of living help
in better control over diabetes and its further ill effects. It could be
adhering to a healthy dietary regimen, workout schedule, foot care,
routine blood glucose level check-up and stopping smoking and
betel quid chewing habit. This adherence is somehow compromised
due to several reasons like unawareness, laziness and not engaging
in diabetes counselling and/or diabetes education programs. These
barriers should be taken into consideration and need to be overcome
to delay the occurrence of diabetes complications. It was found that
88% subjects were not compliant with a healthy diet, 25% towards
routine workout, 32% towards glucose level monitoring, 70%
towards foot care, 6% and 25% towards not quitting smoking and
betel quid chewing habit respectively. A strong correlation was seen
between altered blood glucose levels (both fasting and post-prandial)
and non-compliant behaviour towards a healthy diet [51].
In the research conducted by Bezo et al, a sample of 150 persons
with type 2 diabetes mellitus were registered out of which 10 were
excluded due to multiple reasons. So the experiment was conducted
on the remaining 140 subjects. It was found that the subjects who
engaged in more than 30 minutes of exercise tend to show more
problem-solving and self-integration scores [52].
A study conducted to analyze the effect of anti-diabetic medication
on controlled blood glucose levels found that the patients (83% of the
total sample size) who were adhered to medicines, able to manage
their diabetes properly as compared to those who did not adhere. It
was also found that diabetes treatment, availability of medicines and
systematic diabetes education played a significant role in adhering to
medication [53].
